Hey guys! First post here. Hopefully this is the right place.
I am studying electrical engineering and am building a guitar amp for a summer project class. I have decided to buy this kit. http://www.ax84.com/p1.html
My professor and I want to modify this amp, specifically the tone stack. We'd like to replace the current tone stage with an arduino controlled filter.
So, thinking theoretically. We could build a simple RC flter and replace the resistor with some voltage controlled arduino resistance. My professor has recommend I look into FET's. Considering FET's are voltage sensitive devices, it might be able to accomplish what I want.
I've never done anything like this...so, I guess I am asking for some help! Where should I start? I plan to design and test the circuit on a breadboard with a function generator. Just gotta design something...
