    I got a MXR M87 Compressor pedal today. I hooked it up, and started playing around, trying out all the knobs. Then I hit the switch to turn off the pedal/bypass, and nothing... no sound. The spec sheet says it should be true bypass. What gives?

    Also does anyone know what the ON/OFF switch inside the pedal does? Image below

    Bypass started working, maybe it needed a few dozen switch clicks. The internal ON/OFF switch is still a mystery

    That switch is to turn on / off the LEDs
