“Roland TB 303

Classic analogue synth.

All in perfect working order.

Serviced a few years ago in 2015 by Kent Spong of KSR.

The pots are nice and firm with no crackles.

Hasn’t seen too much use as you can see from the condition of the unit. That being said it does have a couple of minor surface scratches on the bottom and front side of the unit which I have shown in the pictures.

It was midi modded sometime back. This doesn’t seem to sync to midi but can be used to trigger notes. I always used it with a Kenton Pro solo to sync the internal sequencer.

Selling with power supply, din sync (sync24) cable and two mini jack to female midi connectors again as seen in pics. ” Click here to search for synths on eBay

“Chance to own the original classic TB 303 bass line. For that amazing acid sound. good condition for a 35 year old machine that has had plenty of use as most have. (see photos for condition). Fully working i have tested today as i havent used it in about 8 years. tested with batteries as i have no AC adapter. It did work with adapter when i had it in my studio years ago and still should. when tested I noticed a cracking sound when turning the volume but this faded to almost nothing after playing with it for half hour so should completely disappear with more use. it didnt do this when i used it regularly. “ Click here to search for synths on eBay

“This is an original gangster TB-303 thats lived in a non smoking studio environment for the past 5 years in Brooklyn New York. It’s produced for a bunch of records so its had a good life here and I would like to hand it off to someone that can take good care of it. I have a kid on the way and so I have to start becoming a dad. More picks off the TB-303 up soon.

I updated the picks finally. To answer a few questions you may have, heres a bit more info;

– No scratchy pots. All of the knobs work well with out any scratchy noise.
– There is no corrosion in the battery chamber.
– All of the in and out puts work.

– Batteries included. But you have to get your own DC 9v power source.” Click here to search for synths on eBay
