When I was a kid, half my friends were used to digging
into *something* - electronics, car engines, electric
motors, the plumbing, whatever. Today we scare kids off
from such things. I think that's a really bad idea.
Glad you found out you *can* affect the real world without
destroying something!

Correctamundo.

A smaller cap will reduce gain, meaning lower volume but
stays clean longer. Why th other channel sounds different
depends on the circuit and components. I usually go for
different sounds between channels. Does channel two have a
bypass cap at all?

Too late.

You can try dampening the grill cloth then using a hair
dryer on it to tighten it up. Just do it all
evenly, so it tightens up evenly!

Roger that.
