I have several amps which I have built that sound very good. Clones of a Blackface Princeton, Blackface Deluxe, 18 watt Marshall, Matchless Spitfire, and Dr Z Carmen Ghia. All of them sound very much like their DNA should make them sound. Been playing with a guitar player who is a very competent picker and has been playing guitar for 40 years but has always played acoustic, not electric. No mater what electric guitar or what amp he plugs into, it just sounds bad. I can plug in, play something, then hand it to him...he plays the same thing and it sounds different. We have all seen or heard of great players who can pick up any guitar plugged into any amp and sound good. It seems to go the other way too.
