Tone Control Section
Tone Control
– These three controls allow
you to boost or cut the tone at the desired
frequency. The spacing allows the controls
to interact smoothly and musically.
.
Bass
– This traditional shelving tone control
provides 15 dB of boost or cut at approx. 30
Hz. The control is flat in the 12:00 position.
Mid Range Control-
This covers the central
portion of the sound envelope and can be critical
to getting your sound right. The body of the Bass
sound is in the mid range.
Mid Shift Control
– Provided to shift the
midrange control from low mid (550Hz) for
general playing and recording to the high
mid position (2.2K) for Rock and more
aggressive tones.
Tone Bypass Control
– Located beneath
the tone control. A great tool for recording.
This bypasses the tone section only and
does not effect the boosters or the
compressor.
Treble
– This is a traditional shelving-type
tone control. It provides 15 db of boost or
cut. The knee of the filter is at approximately
2KHz. The control is flat at the 12: 00
position.
Master Level Control
– Adjusts overall
system output and stage loudness.
Headphone Jack
– It accepts a standard
¼ stereo or mono headphone plug. It can
also be used as a Master output send to
slave another amplifier.
