OPERATING INSTRUCTIONS
POWER REQUIREMENTS
The Dual Boost can be powered via 9V battery or 9VDC regulated, center negative
power supply.
BATTERY MONITOR
Upon powering up, the battery voltage is measured. If the voltage measured is lower
than 5V, Dual Boost’s LED will ash 3 times to alert you that it’s time to replace the
battery. Once the 9V battery is replaced, normal operation will resume. Should a battery
fail completely (<4.5V), Dual Boost will switch itself into True Bypass mode and the LED
will begin to ash. This feature ensures that your signal will continue uninterrupted and
undistorted until you can replace the battery with a new one.
Note: The LED ash can be defeated by pressing the footswitch to turn it off.
Dual Boost features two channels, each with individual volume Boost and frequency
Hi-Cut controls.
Boost (1 & 2): Gives your signal a clean boost in volume up to +20dB.
Hi-Cut (1 & 2): The Hi-Cut control is a low-pass tone control that allows you to shave
off high frequency content. With the knob turned fully counterclockwise, there is no
frequency reduction of your tone. With the knob turned towards the clockwise direction,
more high frequencies are reduced. With the knob fully clockwise, frequencies can be
reduced down to 1kHz.
Note: Buffering drives your guitar signal efciently to your amp without tone loss. This
happens when the pedal is bypassed in Buffered-Bypass mode, or is in effect on. The
Hi-Cut knob helps reintroduce the warmth created by high frequency reduction via
cable capacitance in cables when the guitar is plugged directly into an amp without
buffering. Having the pedal in True Bypass mode leaves your signal unbuffered when
your effect is off.
dB Boost Switch
• Left - Sets the max range of Boost 1 and Boost 2 to +10dB.
• Right - Sets the max range of Boost 1 and Boost 2 to +20dB.
On/Off Effects Status Indicator: The LED indicator displays Dual Boost’s effect status, on/
off, as well as the current channel [Green (Boost 1) or Red (Boost 2)].
TRUE BYPASS SWITCHING
Dual Boost allows for True Bypass switching (via relay) which removes the effect from the
signal chain.
