“Roland Computer Controlled TB-303 Bass Line with Original Owner’s Manual and Carrying Case with shoulder strap. Condition Is Used.
I am the original owner and I am selling this unit AS IS, NO REFUNDS and NO RETURNS. I bought this unit shortly after they became available in music stores. I used this unit with the Roland TR-606 Drumatrix. I put it away after sequencers and sound modules became available. I recently placed batteries in it and turned it on (there was some slight static noise when I turned the unit on) and I did some basic programming and the unit worked fine. The unit has some slight abrasion on the front and back panels of the unit which I believe is from the carrying case. This unit was not checked out by a professional technician.” Click here to search for synths on eBay

“These legendary synths don’t need any introduction. If you came here, you know what they are. I have two (!) original Roland TB-303s just standing here collecting dust. They deserve to be used more than I’ve got time for.

The price I’ve put down is roughly what the have cost me, incl. some servicing and upgrades with complete 5 socket Kenton kits for both (CV, filter, gate, accent, slide). I have paid for getting all the services and the installation of the Kenton kits done professionally, but one of the synths was bought from Japan and a couple of lanes on one circuit board was cut to use the original CV/Gate outs as ins. I have got this corrected so that they have the original functionality back, but full control via the Kenton kit in addition. The other one is by me bought here in Norway, but I don’t know if it was bought here originally.

A Kenton Pro-2000 mk2 can follow the sale (midi-CV/gate converter which can also control accent, slide, filter). All leads to connect both synths to the controller will be included.

Sound wise the two synths are quite different. The one has a very nice sound, the other has way too long sustain and I have not been able to get this fixed. At the moment you can not make the classic 303 baselines with it. Hopefully someone with experience tinkering with 303s can get it fixed. All pots work, but they are a bit more loose and scratchy on the one of them. With midi control this is no problem, and I’m sure this can be fixed too. All the electrolytes have been replaced during my ownership, but it is a few years ago now. There should not be any dried out capacitors today, but things change with time of course. I have PSUs for both of them (euro plug), plus the original soft bags, one black and one silver.

This is an unique opportunity to own not just one, but two pieces of music history, even though they are not in mint condition after so many years. During my ownership I have maybe used them 10 hours in total during 10 years. I just need to realise I don’t have the time to use my studio more and they are better off with someone else. When you start playing with these and tweaking the knobs you get lost in time, the hours just fly by, but I don’t have that time. They are fantastic machines.”

“Up for auction is the Roland TB-303

The unit powers and all buttons and functionality works as expected….except the sound is very faint. You can the pattern following along with some noise but it is not outputting anything as you would expect.

I am not an engineer, technician or electronics expert by any means but I suspect it may be something easy to fix.

The unit is in good cosmetic condition however there is a slight crack on the rear of the unit and a small chip on one the of bottom corners.

I cannot find the adaptor for this synth but I tested it using batteries. The Roland PSA adaptor is very easy to find or you could also almost any 9v centre negative adapter.”

“This is the Holy Grail! This particular 303 is in very good condition for its age and construction. Everything works. The filter on this particular unit is excellent I’ve heard some wimpy ones and some buzzy ones but this sits right in between! No mods no touring the writing isn’t all rubbed off like the other 303s you see. This is an excellent example and doesn’t show signs of failure at all.”
