x0xb0x - Roland TB-303 reverse engineered clone. One of the orginal batches, with identical components to the TB-303. Professionally tuned using an Oscilloscope.

It's better than a 303 because it has USB, Midi & multiple 1/4" Audio Jacks.

No power adaptor supplied.

Engineered for Quality

We have two--count 'em, two--analog electrical engineers with too much time on their hands working on this project. An original TB-303 was diassembled and reverse-engineered to verify the schematic. The original transistors were analysed using big expensive curve-tracers to determine their characteristics. We measured every waveform and counted every cycle to give you the best sound...its just like the original because it IS the original.

Obsessive-compulsive? Well he is German

Our crazy German engineer obsessed over EVERY GODDAMN THING in this synth to make sure it was perfect. We sourced all of the original transistors and op-amps, even though it took months of harrassing people on the phone. Just deciding on which potentiometers to go with took three solid weeks of searching through catalogs. (Its a good thing he's unemployed or he would have been fired for not leaving the house.)

Computer Controlled

Plug this baby into your computer, using a standard USB port. Our Java software will control the x0xb0x, or let you save/edit stored patterns and tracks in the onboard memory.

Input/Output

x0xb0x has all the I/O you could ever need:

• MIDI in, out, and thru

• DIN Sync (in or out, selectable)

• CV and Gate (1/8" jacks)

• Audio: headphone, mix-in and line-level out (1/4" jacks)

• USB for computer interface & control
