Control set
Phase switch
Use the phase switch to improve bass response at low volume or to control
feedback at high volume. Play your guitar and toggle the phase switch back
and forth until you achieve the desired result.
Volume
For the cleanest signal, set the volume as high as possible without clipping
the next device in the signal chain. If you hear distortion and the clip/batt light
is not fl ashing, reduce the volume.
