“Up for auction is this rare and highly sought-after Roland bass synth, the TB-303 model. Don’t miss out on this rarity at no reserve, no buy it now! It will simply go to the highest bidder.

Condition Report

The unit has some signs of use, light scratches and markings to it, but overall looks good. Please examine the photos below and judge the condition for yourself.” Link

“This is a well used, but fully functional original Roland TB303. It has had no enhancements or anything as far as I know, but another ebayer told me it had extra outputs etc on the back, which is a good thing. You can see in the pics that some of the paint has worn off on some of the knobs. However, everything feels tight and correct – none of the buttons are loose or falling off or anything. All the lights work, all the connections are functional etc etc. I have only ever used the 303 connected to a Kenton so that it functions via midi. I don’t have the instruction manual but it comes with the original silver carry bag. It also comes with the power supply that I have used with it for the last few years. It is not the original Roland power supply, but it works perfectly. I have been told this 303 is modified as it has additional inputs and outputs on the back. I have included the CV & Gate cables with this auction.” Link

“I acquired this Roland TB-303 from its original owner, who purchased it for a church band. Needless to say, this synthesizer had been very well taken care of and hardly used. All the lights and knobs are fully functional. One small scratch on left body, as seen in photograph. Everything is original without modifications. Comes with original soft case. Original box is also included but is very worn (as seen in photograph).” Link


Here is a original Roland TB-303 bass synthesizer with built-in sequencer manufactured by the Roland Corporation from 1982 to 1984. Only 10,000 units were ever made!

Serial # 235100

Perfect Working order – Comes with the original soft case and user manual.

There are a few scratches on the bottom of the unit, and some slight wear around frequency cut off knob. Other than that, this 303 is in perfect working order. All the knobs are noise free and everything works like it should. ” Link

“Roland TB-303 in excellent condition, very clean and functions perfectly. This unit has been professionally upgraded with all new tact switches, and blue LED’s. The only thing worth noting on this unit is a tiny crack in the left/front corner of the case as can be seen in the photo.

Unit comes with after market universal power supply, will be professionally packed, and shipped fully insured. ” Link

” I’ll say this straight away – this is definitely one of the best Roland TB-303′s you are likely to find. It’s an unmodified, clean, 100% working example.

I have just had this serviced for sale. As part of the service i had a whole new set of ALPS switches installed (those are the buttons you use for tapping in the sequence etc). I also had all six of the control pots replaced with new ones. In other words, this TB-303 is mechanically like new.

Cosmetically very clean for it’s age asides a few minor scratches (mainly on the underside). The battery compartment is clean with no leakage. There is a little residue from a piece of sellotape on the right hand side of the front panel but this will clean off.

Why am i selling ? I simply don’t use it. It’s a lovely little piece of history to have sitting in the studio but in all honesty i’d prefer someone to get the enjoyment out of using it.” Link

It will be better off in a studio where someone really wants it lol. I have only ever used the 303 connected to a Kenton so that it functions via midi. I have never programmed it, and have no idea how to, but apparently thats possible. I don’t have the instruction manual (hence me never programming it, I suppose lol), but it comes with the silver bag and power.” Link

“This is an original unmodified Roland TB-303.
Serial Number 220700.
I have owned this unit since 1998 (almost 15 years).
I have used it only in a smoke-free environment.
This unit works perfectly and is in excellent condition for a synth that’s about 30 years old!

I always use the 303 with batteries, so I do not have the power supply.
This auction is for the unit only. The manual can be downloaded from the internet. I don’t have the original one.” Link

“If you are unfamiliar with the Devil Fish modifications, this is a mod done by one person on Earth, Robin Whittle, which entails shipping your 303 to Australia. This is version 2.1C. It has the standard “Devil Fish” mods which are an $880 upgrade, the blue LED upgrade at $99 and the 32 banks of memory at $385. A total of $1364 in upgrade/modifications. If you were planning on sending yours to be modified you would save money, time and worry by buying this one. The photos are an honest representation of the units condition. Battery compartment is clean. It sounds amazing. ” Link

“Up for sale is my Roland TB-303 Bassline.

Looks and sound amazing!

As you can see from the photos it really is in very nice condition, an excellent addition to any studio or collection.

Recent service that includes all pots & input/outputs cleaned.

The battery compartment is clean and free of corrosion – the body is very nice with only a small chip to the corner plastic, see photo.

Some small marks here and there, the overall appearance is excellent.

I’ve seen these TB-303′s sell on eBay for over £1750 so grab yourself a bargain.

Also included in the sale, original carry case and new Boss power supply.” Link

Regretful sale but I’m reluctantly and urgently letting go of my beloved devilfish in order to fund my travels. The 303 was modded last year by Robin Whittle and is an incredible machine!!! The 303 was also full serviced, completely cleaned internally and fully serviced. There are some signs of wear on the back of the case but internally the unit, boards and components are completly clean and in perfect condition as said by robin whittle. It has some wear around the knobs but there are no scratchy pots and its 100% fully functional with no problems at all and it sounds incredible!!!!! The devifish comes with the original roland carry bag, dyn sync cable, devilfish modification input and output cables for further exploring the modifications and a System J Synthesizers DS-3 Din Sync Router for splitting a dynsync signal. This is one of the most fun synths I’ve ever played with, the devilfish mods expand the capabilities of the basic machine by about 700 percent! ” Link

“This is an original Roland TB-303 Bass Line synthesizer with built in sequencer! This is a very rare and sought after synth originally released in 1982, no need to describe this one as if you are looking at this auction, you know what this synth does and what it’s capable of, especially in the genres of dance, house, acid, ambient and trance music.

The unit is in very good condition all around with light signs of wear. There’s one scratch on the rear (by the connectors) – outside of that, nothing major. All buttons and knobs work perfectly. The battery compartment is completely clean. All connectors in great shape.

The unit powers on perfectly on batteries or via the supplied power supply. The Roland/Boss PSA-120S power supply is a well regarded power supply for this unit – it supplies clean regulated power. If you choose batteries, it requires 4 standard C-Cell batteries (not included).

The unit passes and plays audio with no issues. I played around with it for a while and verified that the knobs properly modify the sound of the audio that comes through it. All controls that I tested seemed to respond properly.

Auction Includes:

Roland TB-303 Bass Line Synthesizer
Roland/Boss PSA-120S Power Supply (new)
Original Manual
Padded Carrying Case” Link

“Up for auction is this absolutely stunning condition Roland TB-303. This unit has been restored and is in absolutely remarkable condition. It works perfectly and sounds great.

This thing produces brilliant bass lines and is a very very much increasingly rare unit to find, especially in this condition.

You may note that the colour scheme is a little different to what you would normally expect. This is to do with the restoration process but of course does not affect the functionality of the unit.

The bass sounds this produces as well as other sounds are rich and funky. You can get some great acid sounds out of this thing and it is easy to programme bass lines.

Everything works on this unit perfectly and all the buttons and knobs work very well indeed.

The power supply is not the original. The power supply is a very good quality universal power adapter with the correct settings for this unit to work. We have supplied this universal power adapter with the unit.

The power supply is, as would be expected a 240v adapter which converts to a variety of voltages including the 9v required by the TB-303.” Link

“Great condition TB-303. As you can see, there is no wear around pots or on the buttons. No corrosion on the battery contacts either. The pots turn well, it sounds great. It’s had little use and abuse over the decades. We used it to reference test our x0xb0xes, which goes some way in explaining their great sound.

Included is the synth, a modern regulated power supply (which provides a more stable voltage than the original simple transformer and works at both 110v and 220v), and a hard copy of the manual. Unfortunately we did not receive the battery cover when we bought it, but a new replacement is available on ebay.” Link
