Front Panel Controls:
Master: The master controls the overall volume of your amplifier. The higher the setting, the louder the output and
tube saturation. . Start off setting the control at around 9 o’clock am and then dial in your rhythm control in the clean
channel until it begins to distort. This will be a good reference for your rhythm channel. Pull the master control and then
dial in your gain control for the amount of distortion.
Bass: Use this control to dial in your bass frequency’s. Depending upon your pickup configuration, single coils will
require more bass and humbuckers less.
Mid - Use this control to dial in your mid range frequency’s. Mids are the most active part of the eq circuit, cutting
scoops your tone, sort of like creating a “V” in a graphic equalizer. Boosting them will add presence.
Pull Modern: This radically changes the eq of your amplifier. Pulling this control will slightly reduce the mids while
raising the bass and treble frequencies. Works best in the drive mode with mid control at minimum settings.
Treble: Use this control to dial in your treble frequency’s. Depending upon your pickup configuration, single coils
will require less treble and humbuckers more.
Drive: This controls the overall distortion of your amplifier. We reccommend setting the drive control at 9 am and
slowly dial it in until you are satisfied with your overdrive. Lower settings will offer more of a blues type of gain,
mid settings are good for crunch and higher settings for metal. Use your master to add girth to the drive control,
(notice how the amp sustains a note longer when the master is turned up).
Rhythm: Use the rhythm control to adjust the gain of your clean channel. The higher the setting, the more distortion
you will add to your signal. We recommend starting at around 1 o’clock. As you rotate the knob clockwise
listen to your signal until it begins to distort. Dial in the amount of gain according to the syle of music you play.
Pull Brite: This control adds presence to your clean channel. Use this to create shimmery clean tones and to give
your treble a boost when using guitars with humbuckers and darker sounding woods.
Input: This is where you plug in your instrument.
Footswitch: Plug your single button footswith cable here to access both the rhythm and drive channel of your amp.
If you forget your switch at the gig, you can pull the master control to access the lead channel.
