FAT32 Dynamic Filter



Compare to BOSS FT-2™ from the mid 80’s, using the obsolete dual VCA M5207L01 chip. Dual  stacked PCBs, meant to fit inside the 125B enclosure. Comes with 1mm spaced M3 nylon washers, and color-matched mini 3pdt pcb (if available). Link to mini 3pdt pcb.
This can be built with only the “up” or “down” options, or with a rotary offering an additional “manual” setting that allows cocked wah sounds and/or an expression pedal out via a stereo jack.
Can be purchased as pcb set (both pcb’s with mini 3pdt pcb), or the very same bundled with a tested M5207L01 chip.
