Hey ok,
I didn't want to start another post for this because I'm not intending to build it it's just for the interests of learning.
Ok I was trying to think about how a Tremolo Effect works and I thought that the following circuit might work...
It's sort of hard to explain but the general Idea is that the NPN Transistor acts as an automated variable resistor and as a fluctuating current is passed to it through the base (I think) then it will either be loud or quiet depending on the strength of said signal. So for the part that says Oscillator I was wondering how I would go about making well an oscillator from like 0 to 5 or so volts.
My thoughts are that I should have a capacitor charge up and then expel said power...but I don't know it that would get me what I want.
