Home made guitar amp overdrive

Post by RockNRoll! » Wed Dec 01, 2010 8:44 pm

I killed an old toy I had laying around to use it's amplifier chip to make a guitar amp using the diagram in figure 16. I wanted overdrive so I took the output from one channel and connected it to the input on the other channel so now it has tons of distortion but it's a little too much so I want to hook up an overdrive knob. Would I just make a simple voltage divider like the one below with a potentiometer or is it more complicated? Any idea how many ohms the pot should be? Also would it be possible to make the input a little more sensitive? It doesn't pick up the guitar if it's it's playing a quiet note like tapping.

You always want to put the volume control on the input, never the output. You do use a voltage divider like you have there, but have the top pin come from the guitar, the middle pin go to the amp input, and the bottom pin to ground.
