High Gain input
This is a high-sensitivity input. If your guitar has hot pickups, then plugging into it makes
it easy to overdrive the preamp section, creating harmonic distortion. Guitars equipped
with low-output pickups seem hotter than usual when plugged into this input.
Low Gain input
This is a low-sensitivity input. Guitars plugged into it have more headroom before
distortion sets in (meaning that you can crank up a channel's volume a little louder
before you experience preamp distortion). This is a good choice for a clean overall
sound, and is especially well-suited to active pickups or guitars equipped with preamps.
Channel 1
Both channels are voiced differently, and Channel 1 is definitely geared toward creating
impressive overdrive (think of a "British" tone). Grit, grunge, dirt--whatever you're
looking for in the distortion department is here, from sweet and singing to hard-driving to
maximum sustain. Note: Like the controls on all classic amps, the Treble, Middle, and
Bass interact, creating smooth, musical tone changes. All three controls operate with
even response throughout their ranges.
