Made a loop switcher for my undergrad senior project
Hey Y’all, this is my first post on here in a while. Unfortunately I haven’t really had time or resources to make any awesome pedals for a while. But I wanted to do something related to pedals for my senior project. So we (me and partner) made a loop switcher using 4-1 multiplexors and an arduino to control the muxes. You can chain whatever pedals are plugged into any of the loops in any order, and can bypass loops entirely if desired. You can also store presets for instant recall of pedal order. We also designed an EQ circuit and put it on a PCB; The circuit controls the level of treble, mids, and bass frequencies, while also giving an overall gain control (-6db to + 3db) and wet/dry mixing per pedal loop. We ended up winning the “best senior project” award in our department for this as well. LMK if you guys want to see a vid of it in action.
