The Amp Guide is growing! We'll be working on the new amp categories over the next few weeks so please bear with us as we pull everything together. Our plan is to have each of the amplifier brand sections with all the same historical information that can be found in the Fender section. So many of our users have asked for schematics for these amps so we'll be putting those up first. Thanks for supporting The Amp Guide!
