  • TB-EFA Rev2

    The TB-EFA Rev2 is the second version of our best selling TB-EFA module. It shares the same ‘3 and a bit’ pole filter circuit as the Roland TB-303. It also provides a complete version of the envelope used by the 303 with decay control. Rounding off the module is the BA662 based VCA circuit which…

  • TB-FX

    The TB-FX Eurorack module is an 8hp effects module that combines both a simple short period delay and gritty overdrive that both compliment the classic 303 tones from the rest of the TB series. EFX1 – Delay Starting with the delay, the module uses the classic chip used in many guitar pedals, the PT2399, which…

  • TB-Seq

    Module News: 5th Dec 2023 – New firmware available The TB-Seq Eurorack module and integrated MIDI interface in the Ge0synchronous desktop semi-modular synthesisers combine standard MIDI note to CV V/Oct, gate and trigger conversion as well as MIDI to CV clock with configurable PPQN (pulse per quarter note) – both in and out. The module…

  • TB-Super-O

    12hp Manual Tune1,2,3 & PW1,2,3 Gain for Sqr1,2,3 & Saw1,2,3 when combined into the Super-X outputs CV Inputs: V/Oct 1,2,3 Audio Outputs: Super Saw, Super Sqr, Saw1,2,3 & Sqr1,2,3 individually. The TB-Super-O came about by accident. While testing a pair of TB-O modules we stumbled across a beautiful phasing effect with the typical slight detune…

  • TB-EFA

    The TB-EFA shares the same ‘3 and a bit’ pole filter circuit as the Roland TB-303. It also provides a complete version of the envelope used by the 303 with decay control. Rounding off the module is the BA662 based VCA circuit which is also controlled by the same envelope as the filter. Like the…

  • TB-EF

    The TB Filter Envelope module is inspired by the filter, envelope and accent circuits of the Roland TB 303. It copies the same 3 and a bit pole low pass filter and most importantly the resonance feedback loop. Like the original it has pots to control the Cutoff Frequency, Resonance and Envelope Modulation. These are…

  • TB-O

    The TB-O shares the same saw-core oscillator circuit as the Roland TB-303. It also generates the distinctive, not quite square using the same technique as the original, including making use of the same transistor types – afterall, the name is Transistor Bass… The module can output four waveforms simultaneously, all controlled by the same single…
