Presence:

The presence control adjusts the high frequency equalization in the output stage. It acts

similar to a Vox-style “cut” control, but only for very high frequencies. It is voiced

specifically to take the “hair” off distortion tones to tame a bright or “buzzy” sounding

speaker. When full up, the cut is essentially out of circuit. It is best used as a final tonal

adjustment to add or remove “bite” from the distortion tone.

Output Level:

The output level control is a unique frequency-compensated master volume control.

Unlike most conventional master volumes, this control doesn't get thin or buzzy as you

turn the volume down. When turned all the way up, it is effectively out of the circuit

completely, so it doesn't affect the full-volume tone/signal path at all.

Pilot lamp:

The pilot lamp lights when power is applied to the amplifier and the power switch is on.

The pilot lamp features a screw-on “jewel” that can be removed from the front panel to

replace the bulb without having to remove the chassis. The bulb is a standard #47

“bayonet” style bulb, available at most electronics supply stores.

Power switch:

The Power switch turns the amplifier on in the up position and off in the down position.

Glory switch:

What good is power without the glory? The Glory switch allows muting of the amplifier

output when not in use. When the switch is in the up position, the amplifier is on, and

when it is in the down position, the amplifier is on standby. The tube filaments remain on

and warmed up, so the amplifier is ready to play as soon as it is taken off standby. The

correct powerup sequence is to turn the amplifier on with the power switch and then, after

it has had time to warm up, the Glory switch is turned on. When turning the amplifier off,

the Glory switch should first be turned off, then the power is turned off after a few

seconds.
