DESCRIPTION OF CONTROLS
1. VOLUME (VOLUME SLIDE CONTROL)
The VOLUME slider controls the output volume. At “0” it is com-
pletely OFF. At “+12” it is LOUD!
2. BASS (BASS SLIDE CONTROL) 
3. MID (MIDDLE SLIDE CONTROL)
4. TREB (TREBLE SLIDE CONTROL)
The BASS, MID, and TREB slider controls are a 3-band equal-
izer for controlling tone.
The BASS  tone  control is a  normal boost /  cut  shelving con-
trols.
The MID (midrange) and TREB (treble) tone controls are nor-
mal boost / cut tone filters. 
The center detent on these tone controls yields a flat tone re-
sponse.“+12 ” boosts the tone; “-12“ cuts the tone.
5. MIX (AST / UST - UST XOM SLIDE CONTROL)
Your guitar is equipped with the exclusive B-Band XOM™ mix 
control and two pickups - the UST (Under Saddle Transducer) 
pickup and AST (Acoustic Soundboard Transducer) pickup.
The UST pickup is under the saddle of the guitar. This pickup 
gives full range tones and is the fundamental sound that is al-
ways present in the sound mix. 
The AST pickup is  attached to the  bridge plate or the sound-
board of the guitar. This pickup adds some extra sonic tone and 
adds that tone to the mix.
XOM is an acronym for Cross-Over-Mix. This function is at the 
“MIX” control of the guitar and its use is described below. 
When the mix control is turned all the way towards the (XOM) 
UST / AST side, which is the XOM position - a 50 / 50 mix of 
AST and UST is heard. This is the crossover mix of the AST and 
UST. The crossover point is 800 Hz. From 800 Hz and up is AST. 
800 Hz and down is the UST. 50% is the high tones of the AST 
and 50% is the low tones of the UST. See diagram below.

When the mix control is turned all the way towards the UST side 
the sound is ONLY the UST pickup sound. Full range sound of 
the UST. No AST sound.
With the mix  control at any  position you  always  hear the  low 
tone  part  of  the  UST  pickup.  This  provides  a very  round  and 
solid low tone sound at any position.
