Tone contour is accomplished through passive controls for Bass, Mid, and Treble on the Clean channel, while the Rhythm and Lead channels utilize Peavey’s exclusive Bass, Middle, and Treble active controls. Designed to work equally well into 4, 8, or 16-ohm loads, matching this monster to a cabinet is limited only by your imagination. FEATURES • Three 12AX7 preamp tubes • Four EL34 power amp tubes driven by a 12AX7 • Power amp convertible to use four 6L6GC tubes • Footswitchable effects loop with independent send and return controls • Damping switch (tight, medium, loose) • Special noise gate circuitry on Rhythm and Lead channels • Line out with level control • Cabinet impedance switch (4, 8, or 16 Ohms) • Heavy-duty power, standby and channel select toggle switches • Classic power status indicator lamp 9 10 11 Front Panel 1 2 3 4 5 6 7 POWER SWITCH This two-way toggle switch applies mains power to the unit. The amber power status lamp (3) will illuminate when this switch is in the ON position. STANDBY SWITCH This two-way toggle switch allows the amp to be placed in the STANDBY mode. In the STANDBY position the tubes stay hot but the amplifier is not operational. Switching to the ON position places the amp in active mode. POWER STATUS LAMP This indicator illuminates when mains power is being supplied to the amp. MASTER VOLUME This control sets the overall volume level of the amp. Once the desired balance between the three channels in the amplifier has been achieved, the entire output level of the unit can be increased or decreased by rotating this control. Clockwise rotation increases level; counterclockwise rotation decreases level. TREBLE This control, on both the Rhythm and Lead channels, varies the high frequency response of the amplifier. It is an active control (shelving type) and allows 15 dB of boost or cut. MIDDLE This control, on both the Rhythm and Lead channels, varies the mid frequency response of the amplifier. It is an active control (peak/notch type) and allows 15 dB of boost or cut. BASS This control, on both the Rhythm and Lead channels, varies the low frequency response of the amplifier. It is an active control (shelving type) and allows 15 dB of boost or cut. 1 2 4 5 6 7 3 8 9 10 11 12 13 14 15 VOLUME This control, on all three channels, sets the overall level of its respective channel. GAIN This control, on both the Rhythm and Lead channels, controls the input volume level of the channel. Rotating this control clockwise will increase the amount of preamp distortion and sustain. CHANNEL ACTIVATION LEDs These indicators signify which channel is active. Lead channel activation illuminates the red LED; Rhythm channel activation illuminates the yellow LED; and Clean channel activation illuminates the green LED. TREBLE This passive control regulates the high frequencies for the Clean channel. MID This passive control regulates the mid frequencies for the Clean channel. BASS This passive control regulates the low frequencies for the Clean channel. INPUT This 1/4” jack is designed to accommodate most any guitar output signal. Input signal gain can be adjusted by the GAIN (9) controls (Rhythm and Lead channels only). CHANNEL SELECT SWITCH This three-position toggle switch allows selection between the amplifier’s three channels. LED (10) illumination indicates which channel is active. Channel switching can also be accomplished by footswitch. See the FOOTSWITCH section of this manual for explanation of switch operation. The CHANNEL SELECT SWITCH must be set in the Lead position in order for the footswitch to operate properly. 9 11 12 13 14 15 10 8 12 13 Rear Panel 1 2 3 4 5 6 7 EFFECTS SEND LEVEL This calibrated (0 – 10) control sets the level of signal being sent to external effects and/or signal processors. Clockwise rotation increases the amount of signal being sent; counterclockwise rotation decreases the amount. For the quietest operation, the EFFECTS SEND LEVEL should be set as high as possible. Generally, the SEND and RETURN levels should be set oppositely. If the EFFECTS SEND LEVEL is set low, the EFFECTS RETURN LEVEL (19) is set high to achieve unity gain. If volume boost is desired, turn both controls to higher settings. EFFECTS SEND / EFFECTS RETURN These 1/4” mono (TS) jacks allow signal to be sent to and returned from external effects and/or signal processors. Using shielded cables with 1/4” mono (TS) phone plugs, patch from EFFECTS SEND to the input of the external device, and from the output of the external device to EFFECTS RETURN. Only devices that do not increase signal gain should be used in this effects loop (chorus, delay, reverb, etc.). If the footswitch is used, the EFFECTS SELECTOR (33) switch must be depressed to activate the effects loop. See the FOOTSWITCH section of this manual for explanation of switch operation. EFFECTS RETURN LEVEL This calibrated (0 – 10) control sets the level of signal being returned from external effects and/or signal processors. Clockwise rotatio...
