    I have knowledge of how a guitar amplifier works, and have even designed schematics for tube amplifiers. Even though the general layout (input—>preamp—>fx loop (if wanted)—>power amp—speaker out) is kind of straightforward, what could I add to the circuit to make my design sound different from others?
    Example(s): If I’m making an EL34 amp, make it sound different from a Plexi, JCM800, Hiwatt Custom 100 or Vox AC50, if I’m making a 6v6 amp, give it a sound different than a Fender Twin/Deluxe Reverb/Champ, or if I’m making a 6l6 amp, sound different from a Fender Hot Rod Deluxe and Mesa Boogie Dual Rectifier.

    look up tone stacks [ for all the brandes] and power tube biasing [hot/cold] and their effect on the output

    Transformers have different characteristics that translate to different sounds.

    That’s a lot of what Garnet’s book covers.

    The power supply design, tube or solid state rectifier, how stiff that is, the phase inverter topography, where you put the tone stack, the values in the tone stack.

    Hey a book. Good idea! I had the Garnet book signed by Gar: "first one sold". I gave it to a guy who knew what he was doing.

    Check out Kevin O'connor's "The Ultimate Tone" series as well.

    If you could have one amp, which would you choose, 'Classic' or 'Unique' with no further qualifiers?

    That doesnt tell me how much gain each has, so I cant answer that one.

    EF86 preamp tube into a 2 or 3 band tone stack (not a 6 position switch) and then into a parallel SE power section (so no PI), with a variety of power tubes. I don't know if it'll sound any good but I'm not aware of anyone building that config. But maybe there's a reason for that.

    EF86 doesn't like traditional tone stacks, loses too much gain. It's either a switch or a few variants of a simple tone knob. I use a cathode follower after the EF86 a la Marshall, Fender Tweed, Vox, then into the tone stack. IMHO what makes amps sound different is in what order the signal blocks are arranged, ie gain, tone, cathode follower, gain, PI or another order. Also which PI is used has a big influence on tone. Orange uses a different PI than Fender and others and sounds unique. Many, many ways to "skin the cat".

    A unique sound that is GOOD would be my choice, Doug.

    GOOD = rich, clear, responsive, articulate, variable.

    Otherwise, yeah, may as well "go-with-the-usual." I guess.
