” For sale is a rare Roland TB303. It’s in excellent near mint shape and fully functional. Only minor signs of wear on the unit and the bag. All the knobs turn smoothly, scratch free and buttons are all triggering properly. Super hard to find a 303 that performs are perfectly as this one. You won’t have any issues with buttons double triggering or requiring firm presses, programming on this is a breeze. No wear around the knobs which shows it hasn’t been used for intense filter or knob twisting action. No rust or grime or mildew funky smells either. Even the bottom looks great. I only found some minor signs of wear on the sides which was likely from rubbing against the bag over the years. Check out the detailed pictures to make sure you like it. The battery compartment is clean, no battery leakage anywhere. The 303 is a must have for acid, techno, dance, electronic, hiphop and more. Especially awesome when paired up with a TR606, TR909 or TR808. Don’t miss out on this classic synth!” Link

Roland, TB-303 @ 01 January 2017, Comments Off on Roland TB-303 with Borg Mod

303 “Excellent condition 303 with Borg modification undertaken about 15 years ago by Tom Carpenter at Analogue Solutions.I would like to point out an issue that I thought was a problem but may not be after all.

There seems to be a very low hiss every time a note is played.The hiss is not present when there are no notes generated, but when the 303 is running notes especially when the frequencies are high and resonant it’s not noticeable.

I sent this 303 back to Tom to listen and check it over in 2011.He informed me that this is normal due to it being so heavily circuit bent and that it was behaving pretty normally.He did not open it up however claiming that he didn’t want to disturb the electronics unnecessarily.

Also a slight crackle when the “overdrive” knob is turned down to zero.Since having the mod done i never tested any of the other functions added to the machine apart from the four added control knobs as I never had extensive knowledge of how to use the extra features.There was some minimal battery leakage from the previous owner but this has not affected the performance of the battery function.

Whoever the next owner is I would ask you to check it over first,especially the external vcf connections.” Link

tb303 “Ich verkaufe schweren Herzens meine Roland TB-303 Bass Line.

Die TB-303 wurde von 1982 bis 1984 von der Firma Roland produziert. Da nur 20.000 Stück hergestellt wurden, ersteigern Sie hiermit eine wahre Rarität.

Der optische Zustand der TB-303 ist aus den Bildern ersichtlich. Die TB-303 habe ich 1994 über die Zeitschrift Keys gekauft.

Die Gebrauchtspuren waren bereits vorhanden. Seit meinem Besitz war die TB-303 lediglich in meinem nichtraucher Studio behutsam im Einsatz.

Zu der Roland TB-303 verkaufen ich zusätzlich folgende Ersatzteile:

– 17 Drucktasten
– 6 Potis (Accent, Tuning, Env Mod, Cut Off Freq, Volume, Env Decay)
– Batterieklappe
– Blaue LEDs
– IC 4001 Quad Gate Chip
– IC MC14174B Flip-Flop
– IC D444C 1k SRAM Chip”

tb303 ” Roland TB 303 in very nice condition. Sparingly used in smoke free studio always kept in its case. Works very smooth and has a fantastic sound.

Comes with an installed Kenton mod which adds sockets for:

CV – provides Volt per Octave control over the oscillator frequency
Gate – controls when notes play (0 volts = note off / >3 volts = note on)
Filter – controls the cutoff frequency of the low pass filter (from aux out of converter)
Accent – turns on or off the accent feature (0 volts = accent off / >3 volts = accent on)
Slide – turns on or off the slide feature (0 volts = slide off / >3 volts = slide on)

It also comes with the Kenton Pro Solo MKII control box which is the hub in between your DAW and the TB 303. This way you can control the TB 303 from your computer in ways not possible just using a 303 as stand alone.

Power supplies included for both TB 303 as well as Kenton Pro Solo MKII.

Lastly the original black vinyl case is included. ” Link

tb303 “Hey guys, I’m selling my 303. Previously bought this on eBay from the original owner about 4 years ago. This synth needs no introduction. Currently just downsizing my studio gear. Synth is still in decent condition. Normal wear and tear on it. Scratch on bottom. Knobs are in great condition. Only con on this synth is the lack of the battery door. It had been lost during shipping on the way to me from the previous owner 🙁 however, that hasn’t hindered it’s acidy goodness. Please refer to the photos for cosmetic wear and tear. I’ve been using it through an old gritty 6ch mixer and getting great results. Hoping this will find a nice, new home.

Fairly average condition, with small crack of the plastic on the side as pictured which could do with supergluing down (me and glue don’t mix so not getting involved). Various other marks on the casing as per photos.

The sticking point in this new age with the 303’s was attempting to slave or incorporate into your modern set up without the DIN function….in step the reputable QUICKSILVER CPU!!!

USB connection to slave with your chosen DAW giving you the full sync and editing ability from your PC or MAC whilst retaining full hands on control.

As usual has some minor mark on the casing as seen on the pictures but the face is clean with no pot fading, and printed letters clearly visible and legible.

Comes with a non original power adapter and Roland carry case.” Link

Roland, TB-303 @ 24 July 2016, Comments Off on Roland TB-303 with Beast Mods

303

This auction is for the Beast Modified Roland TB-303. With power supply for UK 240v.

There are only a few analogue synths that sound like a real TB-303. There are even fewer TB-303s that sound like the Beast. While I’m sorry to let this Beast go back into the wild, I’m just not making music very often these days. The Beast thrives on regular excersise.

This machine is rare.

It has custom inputs for Pitch C.V, Gate, Filter frequency, Accent and Portamento.

It has an input allowing external signals to pass through the envelope – imagine a PWM modulated square wave or 2 detuned sawtooth waves passing through a 303 envelope. Yes.

It also has a kind of FM synthesis where the filter frequency is modulated by the oscillator waveform. With resonance on max this is similar to modulating the frequency of a sine wave with a square or sawtooth wave. I can’t describe how good that sounds with the overdrive on max. When you hear that for yourself you will understand why it is called the Beast.

For live improvisation work, there is an octave transpose switch plus override switches for accent and slide.

Takes some head-scratching to set up, but it does work perfectly with midi controllers via my Kenton Pro 2000 C.V. converter (not included). I will send my Kenton patch settings to the auction winner; they will save you much confusion.

My custom knobs are optional. Just let me know if you want them and I’ll include them with the original knobs.

Happy Bidding!

p.s. The tape on the under-side is easily removable without leaving marks. In the pictures it looks like there is a white mark next to the TEMPO on the left, but I just checked the unit and the white mark is not there. I dare say some of the other marks might rub away but I didn’t clean the unit.” Link

tb303 “Up for auction is an ORIGINAL Roland TB-303 Bass Line with the original carrying case and power supply.

It is in perfect operational and great cosmetic condition.It was acquired in 1998, and was only used about 3 times total.

It was stored in a professional smoke-free studio and is from the personal collection of Grammy Nominated producer Chris Cox, who has worked on official releases for Rihanna, Katy Perry, Britney Spears, Janet Jackson, and many others.

Included is the original carrying case, which is quite rare.
I have also located and am including the original power supply, however it is not pictured.
It runs perfect on C Batteries.
There is a slight wear on the printing of the frequency and resonance knobs, which is common since those are the most used knobs.

The Roland TB-303 Bass Line is one of the most coveted and sought-after sound modules in the history of electronic music production. It IS the sound of acid house, techno, and continues to be relevant year after year. This particular unit was cared for, but unfortunately not used (certainly a waste of a great piece of gear!).

It has been tested and works, and SOUNDS, great!” Link
