My old 77 JMP well it was just so simple. You plug in the cord to the guitar, then the other end into the amp and it always sounds the same.....great. You don't have to do a search mission to make the amp sound great. It just always does. You can turn the treble, mid, and bass knobs and it changes the tone a little, but never far from it's great core Marshall tone. My friends JCM 800 is the same. It always sounds like a great Marshall. My Classic 50.....exact same thing. Plug in and play. It you turn the bass knob up more...well it sounds just like it did only with a little more bass. The rectifier.........took tweaking. Next day same settings......not just a different tone....sounded like a different amp! Played a Diezel......same deal, had to keep fiddeling with knobs to "DIAL IN A GOOD TONE". Now that I'm an old fart I've realized I like most Marshalls and simple amps that you don't have to "dial in a tone". So, what are the amps that only use tone controls to add or delete a little bass, mids, or treble but still sound the same. No long mission to "find a decent tone". Fenders and Marshalls, and Classic 30/50"s? Why should you have to work with and fight an amp for it to sound great? It should sound great the second you plug it in and you only need those tone controls for slight tweaking. Am I all alone on this?
