Hey
would it be possible to, in a guitar, install a preamp, and right after it split the signal chain into three. one would be dry, one would encounter a diode followed by a capacitor to block DC ( i think ) and the third would encounter two such diode-capacitor chains, then blend all three together with blend knobs? this would theoretically allow a musician holding a note/chord to turn up the levels of the octaves and down the fundamental, thereby achiveing a mediocre approximation of standing in front of an amp which has been cranked to hell?
Now that i think about it, it seems kinda trivial/dumb, but could it be done nonetheless?
