(This poll is exclusively regarding your opinion about tone. I’m not interested in which is best for gigging or bedroom volume or any of that. Tone is all that matters here) Early Marshall JTM/JMP Fender Tweed Deluxe/Bassman/Twin Supro 1690TA/1624TA... Silvertone Twin Twelve... Vox AC30, AC50 Hiwatt Magnatone 213 Danelectro Centrium (fill in the blank)___________ First of all, a list of amps with channel jumping ability would be sick! If you know of any (besides the obvious), don’t hold out. I’m interested in the old original circuits, NOT modern clone/boutique rehash amps. Feel free to toss in any original modern 4-holers though. At some point I started to realize that most of the amps/circuits i consider to be the greatest of all time have 4 jumpable inputs. Sure, the entire signal path is intricate and every part of it is making its own impact. That said, I have really come to appreciate the wonderful, complex tone of parallel gain stages working in tandem, creating dynamic tube breakup brimming with character and rich harmonic content. Not to mention the tonal possibilities of mixing Bright and Normal inputs. So, lastly, which do you prefer? Amps that offer the ability to jump Bright/normal channels or all cascade designs (typically channel switchers)? It wasn’t long after guitarists (with balls) started jumping their amp inputs to get more gain and more interesting tones, that amp builders started making channel switchers engineered for dirt. Good ‘ol Leo, on the other hand, went another direction by putting the kibosh on channel jumping and released amps with improved clean headroom.
