“This unit is in perfect functioning order. It looks great and it sounds amazing.

I have owned it for about 25 years, it has rarely left the studio. Before me it belonged to my former band’s drummer, who bought it new and never figured how to use it.

Pretty much as pristine as these can come. You can see it in the photos. The original manual comes with it. I no longer have the original bag, witch was not too protective in my opinion back then.

In the early 90’s I recorded a lot of tracks with it and got to be really good at programming. Though the real fun (what most hits who used it did) is to play with the 128 random generated patterns that it creates every time you take off the batteries.

Over the last 16 or so years it has mostly stayed on its case, kept safe, dry and without batteries. Every time I thought about selling it I loaded the batteries and spend hours having fun, just to realize what an awesome piece it really is.

So, if you have ever dreamed about owning one: here is your chance. ” Click here to visit listing on eBay

“Cosmetically unit looks good (please see photos) but do not know how to fully operate, so am selling as-is. Unit powers on and seems to be in good working order. For what it is worth, I bought this alongside a few other Roland devices — the other devices all work perfectly. Let me know if any questions.”

“Alas, selling my Roland TB-303 analog synthesizer modded with Social Entropy — which allows alternate ways to program the 303, retains pattern memory without batteries, and includes MIDI. I’m sure there are other perks that I can’t recall, but I’m sure it can be found though a Google search. It’s in very good condition and has been serviced by Analog Labs in Brooklyn. See the photos for little superficial dings and chips. Everything still works like a beauty and I will miss this. Because people ask, I’m selling my gear because I just don’t have time anymore to make music after my 2nd child was born. Please no requests to: lowball me, cancel the auction, deal outside of eBay, or give me a lecture on how I should sell this. Serious bidders only. DO NOT BID IF YOU DO NOT INTEND TO BUY IT AFTER WINNING. DO NOT BID AN AMOUNT YOU CANNOT AFFORD. Know your limit. Pay within 48 hours winning the auction or the purchase will be cancelled. Sorry for having to say all this, but this has happened way too often beyond comprehension.” Click here to visit listing on eBay

“Only one available worldwide

Welcome to the extremely rare Devil Fish modified Roland TB 303 baseline synthesizer version 4.1 with MIDI and glitch switches.

197 of 200 made by legendary Robin Whittle and works perfectly.

This is in very good condition both cosmetically and electronically. Kept in smoke-free Hepa-filtered studio with temperate control.

This tb303 is rarely available and the last one to sell on eBay was over 8 years ago.

For a quick summary the Devil Fish has AUDIO IN, so you can run anything you want through the Filter, Overdrive, and Filter FM.

Among the many modifications, the Devil Fish provides enhanced bass response and extremely modified

It is VERY versatile sounding. You can make drums and percussion sounds because the Decay goes lower than a 303 and resonance goes higher than a normal 303.

You can use the filter with Overdrive at “0” (no VCA volume) to make the filter ring and create all kinds of weird chirps and Sci-Fi sound FX that nothing else can mimic.

The sound is fatter than anything I’ve ever heard especially with the Devil Fish Overdrive circuit.

This same machine has been used by artists like Hardfloor and Daft Punk.

Not many people have ever been able to afford one, or now – find one.

For more information please consult the Devil Fish website or just look online.

The power supply is not an original Roland but made for this machine and well-tested.” Click here to visit listing on eBay

“You are bidding on a vintage Roland TB-303 Computer Controlled analog bass synth. This one was bought new (when the product flopped), had never been used, and has been stored since that time. It is new with the original carton, candy, manuals, plastic, and accessories, including the original batteries (non-alkaline). The carrying case is a little gnarly from being stored in Styrofoam in Mississippi, but is all intact. It works perfectly and still has the factory beat installed. You won’t find one like this again! Thanks for looking! GOOD LUCK!” Click here to visit listing on eBay

“The Roland TB-303 Bass Line (also known as the 303) is a bass synthesizer released by Roland Corporation in 1981. Designed to simulate bass guitars, it was a commercial failure and was discontinued in 1984. However, cheap second-hand units were adopted by electronic musicians, and its “squelching” or “chirping” sound became a foundation of electronic dance music genres such as acid house, Chicago house and techno. It has inspired numerous clones.

My unit has been modulated to work with a Kenton-2000 which is included in the sale – this makes the fully compatible with Midi.” Click here to visit listing on eBay

“WORKING CONDITION: Non-Functional- The item does not power on, and was examined and deemed to be too repair intensive to be worth the expense or time to handle for us, so we are selling “as-is”

PHYSICAL CONDITION: Good – This synthesizer is in good physical condition. There are some chips in the plastic on the two front corners. There is also some discoloration and tape residue from aging. All the buttons and controls look in great shape and the synth overall feels sturdy. Internal components appear to be intact. Overall, despite some imperfections, this synth is in good physical condition.

The vinyl case for this is original but is very stiff and aged.

“This 303 is in great condition, with the exception of the fading/discoloring which is typical for its age. All of the switches were recently replaced by a professional technician and programming is a breeze. This unit is completely free of corrosion. The only issue is that the decay pot is slightly stiffer than the rest. Ships with printed manual and ac adapter (not pictured)

Due to its age and the delicate nature of vintage electronics, this unit is being as-is.”

“Roland TB 303 Bassline Synthesizer quicksilver cpu blotchy case see photos.

I bought this 303 off eBay USA in 2008. It sounds great for a 303, I love the sound of it more than the previous 303 I owned and sold in 2005.

It has the quicksilver CPU which is more powerful than the original CPU. But it’s programmed in a slightly different way, you’ll need to get the manuals and cheat sheets on your favourite search engine.

Comes with power supply.” Click here to visit listing on eBay
