I built it for a friend who wanted a LPF for keyboards and it sounds great. For my build I added expression control for the dual gang frequency pot so the user can do frequency cutoff sweeps with an expression pedal. It required a DIN-6 plug and a 6P2T rotary to switch between onboard and expression control. I wired the onboard dual gang pot off the pcb so I could give it a bigger knob. It’s designed for an 125B enclosure but I put mine in an 1590BB2 because of the extra hardware and wiring. Other than that I built it as-designed and it works great. I like that pedalpcb offers options like the I/O power breakout board (which I used) and you can wire the status led to either the 3pdt board or the main effect pcb depending on where you need to place it for your design. Good documentation, took some extra attention on my part to make sure I got the wiring right for the jack breakout but it worked first try. If you want a filter with tone options, this is a good one!
