I made this to use personally to use at the end of my signal chain but it turned out to cool not to throw in the lineup. It's basically a kill switch with latching and momentary switches, but you can also control the amount of signal killed. So it can also be used as a reverse boost so to speak. Passive, simple, effective and inexpensive. Power is only used for LED indication. MCP and me approved. End of line.
SPECS: Smaller 4.7" x 2.6" x 1.5" 125B sized enclosure, true bypass switching, common 9vdc center negative BOSS style power input and battery snap. Current draw 1.5mA. Power supply not included.
