"Braintec Transistorbass 3 Analogue Monosynth built in 1994. Only 400 were made.
A very few knobs are a bit stiffer than others, but apart from that, the unit works fine and knobs don't produce noise when moved. A 12V 500mA AC-Adapter is included but not original. It can do some really good TB-303 sounds (including slide and accent), but it really is capable of much more. Quite complex Midi-Implementation.
Take a look at [link] for some good info + manual.Specs:
2 VCOs:
- VCO 1 is saw/square switchable,
- VCO 2 could work like a LFO, modulating VCF, sync to VCO
Source-Target Modulation Matrix via Pitch bend / Mod Wheel / ENV ...
with 128 configurations switchable with midi program change
2 LFOs sync to Midi Clock
Real time MIDI control with controllers over the most important parameters
Accent (separate to volume) and slide effects to emulate the TB-303
