EXTERNAL CONTROLS & FEATURES

BIAS CONTROL

 – Turning up the bias control will lead the XW-1 to having 

slightly more output & firm up bass frequencies along with a more 
pronounced wah through the sweep.  A cold bias is common with 
vintage wah pedals for a very clear voice that is more transparent in 
tone and smoother in operation.

WAH Q CONTROL 

– This knob adjusts the Q (the width 

of the filter peak) and in basic terms, 
adjusts the amount of the wah effect for 
precise filter shaping to achieve 
vocal-like effects.

TREBLE & BASS CONTROL 

–  A two-band 

EQ with +/-15 dB center-detent 
potentiometers optimize the 
voicing for different playing styles 
and gear.
