INPUT JACKS:
Active input changes the
impedance to the first input tube
to better match active pickups.
Passive input for matching the
impedance for passive pickups.
CHANNEL SELECTOR SWITCH:
This switches between channel 1 &
channel two - performs same function as
first button of footswtich
LF GAIN: Frequency selective gain control for bass
HF GAIN: Frequency selective gain control for treble
GAIN: Overall gain control with the sum of the LF and HF gains
BOOST: Tailors the gain voicing of channel 1 only. Sweep from lower to upper gain boost.
Functions is engaged via BOOST or footswitch jack CH/BOOST activating BOOST LED.
VOLUME: Channel 1 volume control to balance output between channel 2. It affects the
SEND level of the FX LOOP. Proper channel 1 volume setting to start to the 3 o'clock position.
BASS: Passive interactive low frequency equalization for channel 1.
MIDDLE: Passive interactive midrange frequency equalization for channel 1.
TREBLE: Passive interactive high frequency equalization for channel 1.
SHIFT: 3 way switch that shifts the frequency point of the tone stack to better match the
amplifier to different speaker types and room sizes.
BOOST: When engaged in channel 1, BOOST control is active for user controlled gain boost.
In channel 2 it is a preset amount of gain boost.
GAIN: Overall gain control for clean channel. Use this control
along with the volume for ranges from crystal clean to slight
break up.
BRIGHT: High frequency boost that becomes less active as
GAIN control is increased.
VOLUME: Channel 2 volume control to balance output between
channel 1. It affects the SEND level of the FX LOOP.
BASS: Passive interactive low frequency equalization for
channel 2.
MIDDLE: Passive interactive midrange frequency equalization
for channel 2.
TREBLE: Passive interactive high frequency equalization for
channel 2.
SHIFT: 3 way switch that changes the voicing of the clean
channel.
DEPTH: Power amp control of low frequency interaction between amplifier and
speakers.
PRESENCE: Power amp control of high frequency variable feedback.
MASTER: Controls the overall output of the amplifier post EQ
STANDBY: Breaks the output tubes cathodes only. Speaker Emulated output still
functions in STANDBY.
POWER: On/off for the mains.
