This module is a special rerelease of the “Mark 1” Bionic Lester circuit with the unreleased “Mark 2” control layout. The Bionic Lester Mark 1 was first released in 2012, and only had one production run. It uses a rare switched-capacitor filter IC with multiple outputs and four operating modes. The character of the overdrive changes with each mode selection and all are distinctive.
DIFFERENCES FROM THE ORIGINAL MODULE:
- Reverse power protection
- Metal shaft pots, long life
- this time ALL of the knobs are MK2 style
- Resistor network and opamp package substitutions for compact PCB layout and greater manufacturability
- Output mixer and A/B crossfader. A feature from the planned but never designed “Aggro Eddie” expander. Enables more elaborate feedback and overdrive patches.
Features:
- Dual 12dB multimode filter
- Based around rare and vintage switched capacitor filter IC
- Rerelease of Bionic Lester MK1 circuit with MK2 interface and integrated Aggro Eddie mixer expander
- Dual CV inputs for filter cutoff of each filter
- Dedicated input and drive stage control for each filter
- Direct outputs for low pass, band pass, and selectable high pass, all pass, or notch modes for each filter
- Mixer section enables mixing multiple filter types at Mix, A, and B outputs
- Crossfader control for Mix output blends between A and B outputs
- Shared resonance control for either filter, does not self-oscillate
- Alias mode switch selectively exaggerates aliasing at low frequency settings
- Clock for channel B can be controlled by its own clock, the clock from A, or both for chaotic filter clocking fun
