Gain (with channel-select Push-Switch)

The Gain knob regulates the Preamp's volume and works with the Master to set the

level and distortion amount. A simple rule of thumb is, the higher the Gain is set, the

more distortion you get.

Treble (with Pull Bright switch)

This Treble control is similar in operation to the one on Channel 2/3. In addition, it has a

built-in Pull Bright switch. When pulled out, it adds bright highlights to the tone. As the

Gain control is increased past about '5', the bright switch's effectiveness will be

decreased.

Middle (with Pull Notch switch)

The midrange circuit has a slight notch in the frequency spectrum at about 550 Hz, and

turning the knob alters the depth of that notch. Its Pull Notch switch shifts the frequency

center of that notch down to about 250 Hz. (For reference, most 1950s tweed amps as

well as many British amps have their notch centered at 550 Hz, while classic

"blackface" American amps have theirs centered at 250 Hz.). Experiment with this,

especially if you're looking for a uniquely expressive rhythm texture.

Bass (with Pull Contour switch)

The "chunk" and support that form the backbone of your tone come from this control.

Pulling the Bass control out will engage a special "Contour" circuit thereby enhancing

bottom end, especially useful with thin sounding guitars where more bottom end is

required for a great comping tone. Also, when using a singled coil guitar for a jazz or

bebop tone, this control will add the needed fatness to the lower strings.

Master (with Push Boost switch)

Channel 1 has a special EQ circuit that works in conjunction with the distortion circuit to

sweeten the tone. Therefore, the Master knob's effect goes beyond loudness control.

Try it with different Gain and Middle settings to adjust the amount of "singing" and "grit".

The Boost, activated by pushing the Master knob, is a sweet-sounding boost

characterized by a more subtle effect on the harmonics than Channel 2's Boost control

while adding sustain. The Ch.1 Boost helps to drive the power amp, and the best

description of its influence over the tone is that it thickens it.

Channel 2

All three channels are voiced differently, and Channel 2 is definitely geared toward

creating impressive and massive crunch and lead tones (think of it as a great "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. This amp has so much potential gain and sustain, you should not assume that

the Gain controls should be set on a typical '10' to start with. You might try 3-5 as a

starting point. This is also applies to Channel 3.
