Overload

Adjust for best tone. If a Telonics (buffered) pedal is used before the preamp, set
fully clockwise. If the guitar is plugged directly into the preamp, set to taste (5 to
8 for normal tone). Adjustment range is 20 k ohms to 500 k ohms. See FAQ’s

The primary input 1 has two input connectors (front and rear). Insertion of a plug
into the front panel input connector auto-disconnects rear input connector. This
reduces or eliminates possible noise sources.

Secondary input (front panel only) for additional guitar with independent tone
controls.
Output to a volume pedal. This signal is affected by the input gain control, and is
prior to the equalization.
Return from volume pedal and is prior to the Pre-EQ Insert on the rear panel.
Sets the gain for the first audio stage of Input 1. Start at 3 or 4 and adjust as
needed. This gain control affects the level for the Pedal To connector (front
panel) which then also affects the Pre-EQ Insert Send connector (rear panel).
Sets the gain for the first audio stage of Input 2.
Red LED indicator only turns on in a rare instance when peaks are hit. Indication
of soft clipping may occur, but you’ll probably never hear it. This LED indicates
an overload on the input or equalizer circuits for Input 1 and Input 2. Reduce
gain or adjust EQ of active input to eliminate.

)

Controls low frequency response. Start at 0 (flat) and adjust to taste.
CW is boost, CCW is cut. Level is adjustable from -16 dB cut to +16 dB boost.

Sets a boost or cut in the mid range frequencies selected by the Mid Frequency
control. Level is adjustable from -20 dB cut to +5 dB boost.

Sets the frequency at which the Mid Level control has an effect. Several
frequency intervals between 250 Hz and 1000 Hz are marked.

Adjusts the high frequency level. Clockwise (CW) boosts the level of highs,
counterclockwise (CCW) cuts the level of highs. The level is adjustable from -16
dB cut to +16 dB boost. Start at 0 (flat) and adjust to taste.

Increases the high frequencies up to 9 dB and increases the rate of increase in
high frequencies. Start at 5 and set to taste.

Only set this control after you have set the others. This is to be used as a sonic
“shading” control and, like any seasoning, a little goes a long way. Start at
12 o’clock. CW yields a “Mooney” bright aggressive sound; CCW gives you a
mellow, darker tone.

Controls low frequency response. Start at 0 (flat) and adjust to taste.
CW is boost, CCW is cut. Level is adjustable from about -16 dB cut to +16 dB
boost.
Adjusts the high frequency level. Clockwise (CW) boosts the level of highs,
counterclockwise (CCW) cuts the level of highs. The level is adjustable from -18
dB cut to +24 dB boost. Start at 0 (flat) and adjust to taste. As you increase the
treble level (0-+24dB), a presence effect will start to be heard at about +18dB.
