So I just finished building the Mini Heterodyne receiver, and it was working fine when I tested it at the shop, but when I took it home and tried it out on my amp, the gate was completely effed. It would make a constant terrible drowning noise when anything was engaged. It still sounded correct underneath the awful droning noise, but you could barely hear it. It should be noted that my amp at home is a shitty 20w solid state amp. Has anyone experienced something similar to this with this pedal?
