Help with idea

[Aleph Null]

Am I remembering correctly that you want reverb to swell in on top of overdrive?

[LaceSensor]

Not swell in, just "turn on" when a loud enough threshold up front is met (perhaps by an overdrive or fuzz or similar)

Could you do this with an LDR? For example once the input signal drives the LED bright enough the resistor would then switch the verb on or open up another channel for the signal to them pass through? Just a thought. I also have been out of the game a while and the cobwebs in my brain are still pretty thick.
