CONTROLS
The Boost-EQ is a very simple pedal - a clean boost with a simple gain control, and a
two-control parametric EQ section that can be toggled on or off.
GAIN
This controls the gain level of the discrete boost section. Gain ranges from about -6 dB
(about half the input signal level) in the counterclockwise position to approximately 15
dB of gain (about 5.5 times the input signal level) in the fully clockwise position. At the
noon position on the dial, the clean boost provides about 9 dB of gain (about 3 times the
input signal level). The clean boost section has been designed to stay ‘clean’ for most
gain and guitar combinations, with additional distortion usually occurring naturally in the
front end of a tube amp due to the increased input levels.
TILT
This control provides a complete spectral tilt of the pedal’s frequency response pivoted
around a fixed point in the upper midrange - think of it as a ‘seesaw’ frequency response
that can be tilted in either direction. Center detent is flat - moving to the left darkens the
overall frequency response, moving to the right brightens the overall frequency response.
MIDS
This control provides a +/- 10 dB boost/cut in the upper midrange frequencies, centered
at the ‘fulcrum’ of the tilt EQ.
There are many different and interesting combinations of the tilt EQ and midrange con-
trol – take time to experiment with the many tonal possibilities of the Boost-EQ.
SWITCHES
EQ ON/OFF
This toggle inserts or removes the parametric EQ section (tilt EQ and midrange boost/
cut) from the signal path.
ON/OFF
This switches the entire effect circuit between bypass and in-circuit operation, with a
green LED indicating that the effect is on.
