Well aidlook, you seem to be right that I lack understanding of amps. I understand solid state amps somewhat well but I do not get tube amps at all so I've decided to build a solid state amp instead and save the tube amp for R&D.
Now for a new question. I still have my little gem mini practice amp project that I could use for the 10" speaker. What are some circuits for tone, treble, and reverb that I could put in the amp?
