Isys III Controls
Volume • For the cleanest signal, set the volume knob as high as possible,
without causing distortion or feedback.
Bass • Boost here to add depth and weight to the sound of the guitar.
Middle • Turn the middle knob all the way left for a smooth “scooped out”
tone at high volume levels. Raise the middle knob to the right of center to add
midrange “bite” to the sound.
Treble • Boost to cut through the mix. Cut to mellow and subdue the sound.
Tu n e • Use the tuner lights as shown below to tune your instrument.
When the batt lamp lights steadily it is time to change the battery. To conserve
the battery, unplug the instrument and turn off the tuner when not in use.
