OPERATION
INPUT—Standard 1/4' input with an impedance of approximately 500K ohms, which we determined pro-
vides the best response from all pick-ups currently available and is the basis for the smoothness of the
tonal response, consistency of sustain and an over all reduction of tone. Additionally, the precision input
scaling preamp contains a 40Hz, 12db/ocatve high-pass filter and an "RFI” filter to eliminate bleed-
through from radio interference.
CHANNEL SELECT SWITCH—This push-button switch selects between the CLEAN and TUBE-
OVERDRIVE channels. This function uses noiseless dual FET switches for studio quality operation.
When using a single button footswitch in the footswitch jack this button is defeated. (Footswitch not pro-
vided).
Clean Channel—This channel is constructed using a monolithic FET network for natural clean tone. The
tone is natural and open, lending itself readily to any musical style. Whether playing soft or hard, the re-
sponsiveness of the clean preamp is punchy and articulate.
TUBE OVERDRIVE CHANNEL—This channel utilizes a real 12AX7A dual triode preamp tube and
direct-driving the control grid using “servo-feedback" control technology.
TUBE GAIN—This control uses "loop feedback" to control the drive level to the tube over a very wide
range. This allows for many subtle settings that are completely responsive to your individual playing
style. Set for clean or over-drive, this preamp is warm, rich and full of natural harmonies.
TUBE VOLUME—This control sets the overall volume of this channel. The noise floor of this tube circuit
is exceptionally low, even at super-high gain settings.
PASSIVE 3 BAND EQ —This passive network is a more vintage style where all settings start in the maxi-
mum position and then you cut to set the tone you desire. This is unlike active controls which exhibit a
“flat" setting at the 12 o'clock positions.
REVERB—This knob controls the amount of reverb present in the output signal. We have chosen a pre-
mium 3 spring ACCUTRONICS® reverb unit with impedance matched send and receive spring transduc-
ers. The sound is full, the tail decays smoothly and clarity remains solid through the mix range. The re-
verb signal mixes with the Effects Return Signal so that both effects may be used simultaneously. If the
on-board reverb is not desired, just turn the reverb master down to zero.
HEADPHONE JACK—Used to connect standard headphones (8-6W ohm). Inserting headphones here
will turn off the 10” speaker. This is a great feature for silent practicing. This output is short circuit pro-
tected. CAUTION—Protect your ears!!
POWER SWITCH—Tums the AC mains power on and off, indicated by the green LED.
EFFECTS LOOP—This network provides 1/4" send/return jacks for use with outboard signal processing
equipment. The SEND jack provides a nominal -10 db output signal to drive any common effects proces-
sor. This jack can also be used as an unbalanced line output. WARNING!!! THERE ARE NO USER
