HIGH GAIN INPUT (1) Used for most electric guitars and passive pickups. It allows for 10dBV less headroom
than the LOW GAIN INPUT.
LOW GAIN INPUT(2) This input is provided for instruments with extremely high output levels, which may re-
sult in distortion or overdriving of the input stage when using the HIGH GAIN INPUT. If both inputs are used
at the same time, then the input levels are the same and both act as low gain inputs.
PRE GAIN (3) This controls the input level of the amplifier, as it feeds the first gain stage. Clockwise adjustment
of this control will result in a hotter and more "responsive" signal to the amplifier input circuit.
BOOST (4) This remote selectable (via MIDI or supplied hand controller) control provides a smooth and mu-
sically pleasing even-ordered distortion/gain circuit just after the input gain stage of the amplifier. At lower
settings, it provides a subtle "thickening" of the tone and at higher settings, it provides a more lively distortion
characteristic....all very much like a genuine tube circuit in a conventional guitar amplifier.
PRE EQ LOOP (5) These ¼" mono jacks provide a transparent loop for a volume pedal (such as the Budda Vol-
ume/Boost Pedal) or any other desirable pre EQ effects devices. High quality shielded instrument cables should
be used from the SEND and to the RETURN in all cases.
LOW, MID, and HIGH EQ (6) This is an active cut/boost tone control that provides about 15dBV of cut or
boost, per band. Counterclockwise adjustment attenuates a given band and clockwise adjustment boosts, in the
same manner. The controls are to be considered "flat" when these are set to "0".
MID SHIFT (7) This control determines the "center" frequency of the aforementioned MID control and the two
are highly interactive, comprising a semi-parametric midrange control. This adjust the frequency the MID con-
