FRONT PANEL FEATURES

INSTRUMENT CHANNEL (Ch.1)
INSTRUMENT INPUT
Accepts a 1/4" mono phone plug. The input "senses" either a magnetic or piezo pickup, therefore separate inputs or a selector
switch are not needed (as on other acoustic amplifiers).
If you should hear some distortion when using this input, make sure the LED overload indicator is not lighting and don't forget to
check the battery in your instrument.
STEREO INPUT
Accepts a stereo 1/4" phone plug. This unique feature was provided for instruments having a stereo output. For example, some
acoustic guitar players have a piezo bridge pickup and a soundhole microphone. These combine for a stereo or dual output signal. As
well, some pickup manufacturers have a dual pickup system culminating in a stereo jack.
The tip of the stereo input gets routed to the instrument channel. The ring goes to the mic/aux channel. This allows the user complete
independent control of the tone shaping and levels of each pickup/mic system! The two are blended together at the end of the signal

GAIN CONTROL

Proper use of this feature will ensure maximum signal-to-noise ratio (quiet operation) and unwanted clipping (distortion) in the preamp
section. Whether you are using the Instrument channel or the Mic/Aux channel, the following procedure should be followed.

This allows finer control of the proper gain setting for your instrument or mic. In other words, you may notice that the volume changes
more rapidly after the Gain Control reaches about the 11 o'clock position. This is normal.

control also "drives" the effects send signal and internal reverb circuitry. Effects units used in the effects loops should be
able to accept line level signals. If your effect is being overdriven at the input, you can turn down the Gain to alleviate this condition.

PULL PHASE FUNCTION
This function reverses the input to output phase. In the "in" position, the output (speaker) is in phase with the input. In the "out" position,
the reverse is true. The purpose of this feature is to inhibit regenerative feedback. This method is superior to a notch filter as it does
not alter the overall tone.
If your instrument or mic starts to feedback, pull the
distance between you and the cabinet is a factor. Depending on your proximity to the cabinet, changing the phase could actually
cause an increase in feedback.
Most feedback in acoustic instruments occurs in the lower registers. If ample volume is not obtained by using the phase switch or
changing your position in relationship to the amp, try using the tilt back handle feature on the bottom of the cabinet. Y ou may also try
