This is a gizm0x x0x-heart MODs Eurorack module, built in small batches in Japan.
A faithful analog recreation of the iconic Roland TB-303 bassline synthesizer voice, packed into a compact Eurorack format.
It includes the classic analog oscillator, ladder filter, VCA, envelope generator, and accent circuitry that made the TB-303 legendary for acid basslines and squelchy leads.
No built-in sequencer (pair it with your favorite Eurorack sequencer for full control). Black front panel.
Key Features & Improvements by gizm0x:
Extensively tuned and refined based on years of repair experience with original TB-303 units for authentic sound and stability.
Four additional modification switches over the standard x0x-heart:
- Bass Boost switch – Adds extra low-end punch.
- Resonance Boost switch – Pushes the filter resonance further for more aggressive squeals.
- Envelope Modulation Increase switch – Deepens the envelope's impact on the filter for more dramatic sweeps.
- VCF High-Range Shift switch – Extends the cutoff frequency range for brighter tones.
Redesigned PCB for better reliability and maintenance:
- Dual-row connectors to eliminate past contact issues.
- All calibration trimpots moved to the rear for easy adjustments.
- Key capacitors upgraded from MLCC to film types for improved audio quality.
- Internal routing of previously exposed wiring cables.
This module delivers that classic 303 acid sound with modern enhancements and build quality – perfect for techno, acid house, or any modular setup craving authentic analog bass.
