Design Notes:

"Braintec was a small German company. In fact it only produced one product in 1994 which was the Transistorbass 3. It's basically a division of the company Touched By Sound which then very soon split into a shop and another company Music And More (MAM). MAM existed for quite some time until 2004 when it merged with a division of TerraTec. Touched By Sound is still trading, selling high tech synths and equipments in Germany.
One would immediately relate the name "Transistorbass 3" to the famous Roland TB-303. In deed, initially, the Transistorbass 3 started out as a 303 clone, but ended up being something else. About 400 units were produced around 1993-94, all sold to German customers, then when they planned to do international sales, Braintec became TBS & MAM and went on to produce the MB33, which is a slightly more closer clone to the TB-303. Some refer this as the TB-3. but i think TB-3 was the prototype name."
