“Je vends l’une de mes 2 Roland TB-303 BassLine. Il s’agit bien d’une vraie TB-303, avec LE son acid tant recherché en musique électro/techno etc.. C’est du pur vintage !

Je m’en suis très peu servi. Elle est en état impeccable, compte tenu de son âge (sorti en 1982) et fonctionne à 100% ! De légères traces d’usure normale peut-être dans les angles (et encore, faut vraiment regarder de près) et autour des potards du filtre (“cut off freq”, “resonance”, “env mod”) ce qui est fréquent sur les tb-303. Le chassis est globalement propre. Le logement des piles est impeccable. Voyez vous-même les photos !

Elle fonctionne parfaitement : tous les boutons et tous les potards sont opérationnels. Elle a été révisée et midifiée par Kenton Electronics en juillet 2008. Kenton a également changé les diodes rouges par de magnifiques diodes bleues et blanches du plus bel effet en soirée !

La midification Kenton propose 5 sorties séparées supplémentaires en jacks 3.5 sur le côté supérieur (slide, acc, filt, gate, cv). Je la faisais fonctionner avec un boîtier Kenton Pro solo MKII (non inclus dans la vente). Je fournis, cependant, les cables nécessaires à la connexion au boîtier. Il ne vous manque que le boîtier Kenton pro solo ou autre. A noter : La midification fonctionne parfaitement dans Logic pro, quelques bugs de fonctionnement dans Nuendo. Je n’ai pas testé d’autre séquenceurs. La prise de synchro Roland DIN sync est toujours active. L’on peut s’en servir pour la rendre esclave d’une tr-808 ou autre boîte à rythme (c’est d’ailleurs ce que je faisais).

Je fournis également le sac original avec l’inscription Roland, la boîte originale en carton, le manuel français et/ou anglais de votre choix (photocopies), et les cables de connexions midi.

L’objet est vendu “tel quel” (c’est du vintage !), et sans guarantie (je ne suis pas un vendeur professionnel).

Les frais d’expédition seront calculés à la fin de la vente et sont à votre charge (le montant indiqué n’est qu’indicatif). La bestiole sera emballée correctement et expédiée par la Poste française avec assurance sur valeur. Aucun soucis ” Link

“The original techno/house bass synthesiser. Very reluctant sale and I know I’m going to regret it forever…

Bit scratched here and there but nothing out of the ordinary for an instrument of this age.

It has been retro fitted with CV/Gate/Filter/Accent outputs and I will ship it with a kenton pro 2 midi to CV converter!!!!” Link

“For sale I have a vintage Roland TB-303 Bass Line synthesizer. Classic analog synthesizer, the famous machine that changed the world of electronic music!

The machine is in good condition, all of the buttons and knobs turn work and turn smoothly.

Everything works perfectly, no static when turning the knobs.

All of the buttons have been replaced with new ALPS switches on the original TB-303 PCB, you won’t need to deal with sticky or mis-triggering buttons, a common problem with old 303s and 606s!

The case is in good condition, with only a few minor scratches or scuffs (see photos), no chips on the corners. There are two holes on the rear panel that have been filled and touched up where a modification used to be installed (it was removed). Not very noticeable, but there.

There is little or no wear around the knobs from tweaking!

The machine is sold as-is in working condition.” Link

“Vintage Roland TB-303 – Midi modified by Colin Fraser – Amazing
Up for sale is this wonderful TB-303.
It’s in great cosmetic condition… and 100% working condition.
This 303 has wonderful white LEDS. Looks sharp! (& not too bright)
No wear at all around the knobs. This is super clean.
No chips in plastic. Battery compartment is clean.

But the best part is this 303 has been midi modified!
Colin Fraser added his “MIDIBass 303″ mod which allows the following:

- Midi IN Clock Sync from any midi source. Now you can sync this 303’s internal sequencer
to your computer’s DAW or other midi master hardware. It’s wonderful, and perfect timing.

- Midi IN synth control. Locate an empty pattern on this 303, and then send midi notes from
either a DAW or other hardware… and sequence/play midi notes, slides, accents, etc. This is an
excellent way to create unique acid lines that break the 16 note barrier of the 303’s original sequencer.
By far, this is my favorite option on this 303.

- MIDI OUT Clock Sync… Transmit clock to other hardware or DAW

- MIDI OUT Sequencer info… Send & back up your sequences to hardware or DAW.

Full info , manual, etc can be found here:

http://www.colinfraser.com/mb303/

This is truly an amazing TB-303.
To top off, it’s also been overhauled.
It’s been given a bass boost which gives the sound even more power…
and the decay is really nice. I’ve owned 3 303’s before, and this decay is perfect.
You can go from full open envelope to short staccato decay. Extremely flexible.

Included:
TB-303 (w/ midi)
Two custom MIDI to 1/8″ TRS cables
Original Manual
Specified Roland Adapter

Don’t sleep. These don’t show up for sale often.
Especially 303s that look this nice.
This item will be packed with love & care, as if it was going to the Moon.
Rest safe knowing it will float in layers of bubblewrap & be double boxed.” Link

“Roland TB-303 is in 100% pristine working condition. This unit is flawless and only had one owner, who took great care of it. Interesting side-note: This 303 was so solitary that it still has the original programming done by it’s first owner who used it in the “standard” bassline style that Roland intended for the instrument. (see video link below)

This 303 is accompanied by the full kit, and then some:

Original Roland Bag

Scale Circle

The PSA-120S (updated) Power Supply (better than the original)

Fold-Out Card

(Vintage) Personalized Tutorial given to the original owner

This Roland TB-303 is in excellent condition. Serious inquiries only please.” Link

“First I must say I’m so reluctant to sell this item, I love the 303 but haven’t used it for a few years.
I purchased the 303 back in 1986 and its been with me ever since.
For its age and the use its had it is in extremely good condition, The picture should let you see the various marks and scratches but im sure you’ll agree its still looking very good, to be honest the marks look worst on the picture that it does in real life? “i guarantee”.
I had the unit in a professional studio in the late 80’s and it was hung on the wall with a Roland SH-101 and a TR-909 (hence the two holes on the back of the unit).
Fully functional and still sounding sweet.” Link

“Up for auction are a Roland TB-303 bassline generator and a Roland TR-606 drumatix drum machine. Adpaters and manuals are included. (the TR-606 manual is a printout- not orginal.) The TB-303 manual is orginal. The TR-606 is missing the cover to the battery compartment. Both units are working – The TR-606 has a scratchy on/off switch, the TB-303 is sometimes scratchy on the “G” key. ” Link

“The perfect 303! This thing is a beauty and only letting go due to financial needs right now. I originally bought it from one owner who barely used it…..the knobs are PERFECT. I then sent it out to a guy named Colin Fraser who enhanced the bass frequencies, serviced it, and added midi functionality through his MIDIBASS 303 unit. (http://www.colinfraser.com/mb303/). Colin even told me that the 303 I sent was in incredible condition. The pots have no wear on them! You can make them out somewhat in the picture. Also, the battery compartment is also clean….and I have the original Roland carrying bag and power supply..even the manual! The manual is the only thing that shows its age a bit. Anyways, it is all ready to go with MIDI converters included so you can just attach your midi keyboard and it is off and running. To simplify what the MIDIBASS 303 does is that it sends midi note data out and accepts midi note data. One of the best things to do is to create a pattern and then set something to record the midi notes from the 303…like a workstation or DAW…then you can play them back out through the 303. It is very simple and provides that killer bass sound with the simplicity and ease of MIDI.” Link

“ROLAND TB 303
BASSLINE SYNTHESIZER
THE SOUND OF ACID/HOUSE & TECHNO
NUFF SAID!

This machine is 100% operational and sounds beautiful.
Also in excellent cosmetic condition.
The machine was recently serviced by engineers at ‘Singing Cat Services’ – vintage analog synthesizer restoration, repair and servicing.” Link

”
Not only does this particular unit work perfectly, but it has even been modified so that you can control several parameters through a midi controller! That means you are no longer a slave to the internal step sequencer or external drum machine. Either use it as was like a standard 303 or connect a midi-CV converter (such as a Kenton) and run it through your computer sequencing program (Logic etc.) and you can play the 303 freely with your full sized keyboard like it was any other midi keyboard. Record midi notes and even accent, filter, and slide information. Play it back through your sequencer and listen to your box get down! This unit has some cosmetic scratches and discoloration, but has all original knobs and sounds perfect!” Link

“The Roland TB-303 Bass Line is a synthesizer with built-in sequencer manufactured by the Roland corporation from 1982 to 1984 that had a defining role in the development of contemporary electronic music.

The TB-303 (named for “Transistor Bass”) was originally marketed to guitarists for bass accompaniment while practicing alone. Production lasted approximately 18 months, resulting in only 10,000 units. It was not until the mid- to late-1980s that DJs and electronic musicians in Chicago found a use for the machine in the context of the newly developing house music genre.

I am selling this unit for a friend. He is the original owner. It has been used very sparingly over the years and works perfectly. If you have any questions or would like more pictures please let me know and will be happy to assist you.” Link

“Very good shape, especially considering it’s age. This unit has been retrofitted with blue LED’s. Very cool, but the original board will be included if you want it to be all original. We can switch them, just let us know. Will come with a power supply. The bassline works perfectly, and will come with a copy of the manual as well.” Link

“Roland TB 303
Legendäre Acidmaschine

Inhalt: TB 303, Anleitung, Netzteil BOSS (Roland), SYNC Kabel, Original Roland Tasche mit Tragegurt

Zustand:

Gerät ist soweit technisch in Ordnung.

Taster funktionieren alle sehr gut ohne klemmen die LEDs leuchten alle auf.

Die Trackregler funktionieren einwandfrei ohne knacksen.

Batteriefach ist mit Deckel und das Fach wie man erkennen kann auf dem Foto noch gut erhalten.

Das Gehäuse ist noch in einem akzeptablem Zustand, hat allerdings die ein oder andere Gebrauchsspur und an den Potis ist der Rand etwas abgenutzt was aber sicherlich keinen stören wird.

Das Gerät wurde vorher überprüft und gereinigt. (Vorher per Video aufgenommen + Testfunktion)

Als Ersatz lege ich noch Original Regler dazu wenn gewünscht. (Original TB 303 Ersatzteile)

Potis oberhalb laufen sehr gut und ich konnte kein rauschen oder knacksen höhren egal bei welchem Poti.

Wave Schalter schaltet einwandfrei und knackst nicht beim schalten.

Pattern Funktion läuft einwandfrei auch der Speicher reagiert normal.” Link

“I am the 2nd owner of this original TB-303. It was purchased back in 1994 and rarely used in a non-smoking studio environment. It has been boxed and stored up until now. Compared to most TB-303’s sold nowadays, this one is virtually in mint condition.

- ZERO Battery Leaks
- Works via power supply (not included) or Battery operated
- Very minor scuff marks on the bottom of the unit
- Original Box INCLUDED
- Carrying case INCLUDED” Link

“Die legendäre Roland TB-303 steht hier zum Verkauf (ohne Modifikation).

Technisch ist die Roland TB 303 in einem einwandfreien Zustand.

Die TB 303 funktioniert perfekt. Sie ist mit blauen Lauflichtern ausgestattet.

Sie wird mit Batterien geliefert. Das Batteriefach arbeitet perfekt. Betrieb mit einem handelüblichen Netzteil 9 V /ab 200mA ist möglich.

Die Roland TB 303-Tasche ist im Lieferumfang ebenfalls enthalten.

Da Privatverkauf, keine Garantie oder Rücknahme von meiner Seite!! Ich versende SOFORT nach Geldeingang. Viel Spass beim bieten!” Link

“This TB-303 has been in my hands for 20 years. I am the second owner. It has been used and maintained by myself.

There are no battery acid stains and the battery hatch plate is present and functional.

The buttons are all working simply because I have been replacing them as they crap out. Anyone who tells you that their TB-303 is “all original” and working perfectly is full of crap. The original switches failed with very little use and virtually no original TB-303 is trouble free. I have replaced all of the original buttons with new ALPS switches. This is just part of keeping the machine working as a musical instrument.

The Roland “Disco Bag” is from a badly acid damaged TR-606. It has been soaked for 24 hours in a bath of baking soda so that no acid remains, however on the inner part of the bag a crappy bown stain remains. There is no getting rid of it.

The case has some small scratches and bumps from the years of use. Check out the many photographs and see for yourself.

For some reason, in a repair done in 2004, I changed out the RUN, PITCH and TIME leds for blue ones. It looks really neat. Thats really the only reason.

This auction includes real, original schematics from Roland. These are not the photo copies one finds all over the place, they are actually printed on large paper with some colour to boot. They are legible unlike the photocopied ones and very very rare. I also include the common photo copied schematics. The original schematics were ordered from Roland and I had to pay money for them.

The original (not photocopied) manual and quick start card are also included.

There are no mods to the sound or the functioning of this unit.” Link

“Most likely you already know a thing or two about this wonderful little gem. I acquired it just over a year ago but never really have spent the time learning the device and experimenting with it’s sound. The unit comes with the original Boss model ACA-120 power adaptor and a printed copy of the original owner’s manual (original packaging and storage bag unavailable). Functionality: all knobs, buttons, switches, and lights are fully functional and have been tested at the time of this listing however the unit has not had a recent professional evaluation or restoration that I am aware of (none should be necessary). The battery compartment is in excellent condition and the unit will function on battery power (4 X 1.5V cells).

Cosmetically speaking, the device is in very good condition. There are no visible signs of wear on the fron panel (unless you look very closely you might notice the normal wear marks around the dials however they are so minor it’s hardly worth mentioning). There are some light scratches on the bottom side of the case – yet even for a perfectionist such as myself I did not find these to be unsightly – nothing more than a few minor blemishes. There is a very small chip in the exterior (lower left side corner) where the top and bottom sections meet (see photo). I would rate it’s condition 9/10 and say that it might be quite hard to find a 303 that looks this good cosmetically speaking. All of the character letters and symbols are perfectly in tact – no fading or loss of ink anywhere.” Link

“Roland TB 303 Inhalt: TB 303 mit eingelötetem sync-to-midi-Chip, Tasche, Originalkarton, Boss Xtortion/xt-2, Alesis NanoVerb, dazugehörige Netzteile (3 Stück), Midi-Kabel (3 Stück), Klinken-Kabel 6,3 mm (mono) (4 Sütck) Ja, ich verkaufe hier meine heißgeliebte 303.

“You are bidding on a ROLAND TB-303 in great cosmetic and working order. I have had it for 10 years and took great care of it. This machine is modified so it can be used in a midi set up with a kenton pro solo. The VCF (cut off) can be used by external controller or midi as well. No return. ” Link

“Vintage Roland TB-303 in excellent condition. I got this unit in the mid-eighties and used it on a couple studio projects. Has been stored on a shelf since, in a non-smoking environment with batteries removed. I tested it with batteries before listing and it worked fine. The battery compartment is clean never any leakage. I have not been able to fine my manual, but you can download one on line. The serial number on this one is 142200. Comes with carrying case. This is all original NO modifications of any kind. All knobs and switches and jacks solid, smooth and tight. Batteries not included, and will be removed before shipping.” Link

“The Tb-303 is responsible for the well-known “acid” sound, which is typically produced by playing a repeating note pattern, while altering the filter’s cutoff frequency, resonance, and envelope modulation. The machine’s accent control has the ability to modify a note’s volume, filter resonance, and envelope modulation, thereby allowing further variations in timbre. There were a mere 10,000 units ever produced by Roland, between 1982 and 1984. This unit is in great cosmetic condition, no dents or dings, just one minor scuff mark on the back panel. It is 100% functional (all buttons, knobs and switches work perfectly and have no damage). The original Roland carrying case, along with the power supply will come included with this machine. This machine also has the option to be used with battery power, making a great companion for recording on the go. This is a great buy! These machines are rare, and this one is in excellent working and physical condition. ” Link

“ROLAND TB-303 with midi to sync converter, ac adapter and sync cable.
This is the most unique synth ever made, only 20.000 made.

“This listing is for a Roland TB-303 Bassline. The unit is 100% functional and while it does show some signs of wear it is still in nice cosmetic shape. No battery leakage at all and it will come with white LED’s which look pretty sick. It will come with original carrying case and box. Sorry but no power supply or manual. ” Link

“The 303, in 100% working order, tested adjusted with servicing documents.
All chemical capacitors were replaced to bran’ new for item’s long life and to keep original sound.
in good cosmetic order, has some physical damages which won’t change its original 303 sounds.Pix say everything, please request high res pix to see minor cosmetic damages.” Link

“Up for auction is my Roland TB-303. This 303 is full functional on batteries or AC, and sounds great. I have been using it with a SBX-10 to sync with Live, and it works great!

Comes with original bag and Boss PSA-120 power adapter. All buttons have recently been replaced and feel nice.

Now – for full disclosure:

1. There are some thin scratches on the front panel as you can see in the photos (by the Roland logo, and by the volume knob)

2. At some point in this 303’s life, there was a repair done to the main PCB. I looks like it was cracked (near the volume knob), and the tech repaired the traces using jumper cables (see photo). This does not affect operation at all (I didn’t even know for 2 years after I purchased it from a guy in the UK). I had my tech look at it, and he said who ever did the fix did a good job, and he could find no faults at all.

I can supply MP3’s of this 303 in action, YouTube video is available at http://www.youtube.com/watch?v=Py79FwAw9Qg

I have done my best to describe the condition of this 303 to the best of my knowledge, and due to the age of this vintage unit, it is sold “as is”.” Link

Copied and pasted text from elsewhere online. The seller would certainly get more bids if he included more pictures and a description.
