Over the Top Boost
O.T.T.B.

VOLUME:
This controls the overall volume (output) of the pedal.

BASS:
This adds low end girth at higher settings and a warm round smoothness at lower settings

CUT:
What this does is the opposite of what you may think. Turning it clockwise will decrease the higher frequencies and turning it counterclockwise adds higher frequencies.

TREBLE:
Thiswill take your sound from a cutting attack at one extreme to smooth and liquidy at the other.

GAIN:
This varies the overall gain of the pedal from bluesy and mellow to fat and saturated.

STANDARD/CUSTOM Switch:

• Standard: When this is selected the EQ (Treble and Bass) becomes very interactive. As you increase the Treble or Bass, mids are decreased and conversely, as you decrease Treble or Bass, mids are increased just like a traditional AC30 Top Boost amplifier .

• Custom: When this is selected the EQ becomes less interactive like an AC30 Hand Wired or an AC15TB.

You can use the OTTB as a booster pedal to drive the input of your amp by setting the Gain low and the Volume high. Conversely, set the Gain high and the Volume low for an overdrive from the pedal itself.

GAIN:
This varies the overall gain of the pedal from mellow and warm to grinding and ripping or anywhere in-between.
