Hello all. I am looking to design a custom guitar amp for personal use. The problem is, all the information I have researched always leads to me schematics of amps that someone has already designed. I have a degree in Electrical Engineering, so I have a good understanding of electronics, and I have built the 9v Ruby amp already to get my feet wet with amps. I am looking to completely build an amp from scratch without looking up a schematic. Complete design from the ground up. Can anyone tell me where I can find more information on this topic?
