Lead Channel EQ, Post Gain, Channel Select

(9)LEAD CHANNEL EQ

These passive controls allow adjustment of LOW, MID, and HIGH frequencies. The “0” position is maximum cut; the “10” position is maximum boost.

(10)POST GAIN

This control sets the overall gain of the Lead channel.

(11)CHANNEL SELECT

This switch selects the channel (Lead or Clean). The ACTIVE CHANNEL LEDs (6) indicate the active channel — green for Clean; red for Lead.

(12)EFX ADJUST

Pressing this control selects the effect. A yellow LED adjacent to the effect name will illuminate to indicate the selected effect. Rotating this control clockwise changes the parameter of the active effect according to the descriptions below. The surrounding LED ring indicates relative value of the parameter being adjusted.

EFX ADJ PARAMETERS
Tremolo - Rate increase	Funk Wah - Sensitivity increase
Octaver - Wet/Dry mix	Rotary Speaker - Rate increase
Flanger - Rate increase	Phaser - Rate increase
Chorus - Rate increase/depth decrease

EFX amps are built with factory settings loaded into the presets. To return to the factory settings, press and hold both the EFX ADJUST (12) and DELAY (14) controls while turning the amp on.

(13)REVERB

This control adjusts the overall reverb level. The surrounding LED ring indicates level.

(14)DELAY

This control adjusts delay type, time, and volume. Three types of delay are available: SLAP (1 repeat), ECHO (3-4 repeats), or INFINITE (5-6 repeats). The LEDs in each section of the control indicate which type is active and volume level. Pressing the control twice sets the delay time to the interval between presses.

(15)PRESENCE *212 Only

This active tone control boosts high frequencies from no boost at the “0” position to 6 dB boost at the “10” position.

(16)RESONANCE SWITCH *212 Only

This switch adjusts the amplifier’s damping factor. Damping is the ability of an amplifier to control speaker cone motion after a signal disappears. In the TIGHT position, vibration is reduced quicker than in the LOOSE position. The increased resonation in the LOOSE position simulates a larger speaker enclosure.

(17)T. DYNAMICS®

This control adjusts the power amp output level from 10% to 100%. When set to lower levels, the tube power compression simulation will be much more pronounced.
