alecee, I work in a store, and I think you'd be amazed at how many people choose guitars by words, rather than notes. The words "Fender" or "Gibson", written on a headstock, are considered very important.
However, in terms of context, TwinReverb said nothing about evaluating a guitar's tone. He's interested in understanding the physics of it. This, I think, is a worthy quest.
joelap, I hope you're running the MOSFETs at tube voltages, an not vice versa.
