Installation

Warning! Installation of the VTB is meant to be
performed only by a professional repairperson.
. Locate the controls on the top of the instrument's
shoulder, on the bass-side adjacent to the neck.
Check for interference with the internal structural
components, such as the neck block, the top braces
or the lining. When you choose a location, be aware
the VTB knobs must clear the interior lining of the
guitar case. The single-shaft control is for volume
and the dual shaft control is for bass (outer knob)
and treble (inner knob).
2. Reinforce the mounting area with a backing
strip of thin veneer glued to the inside of the
guitar. Use the included drilling template to size
the backing strip.
3. Fasten the template to locate
