LUMBERJACK

Congratulations on your purchase of the LUMBERJACK, the revolutionary new log

overdriver by ELECTRO-HARMONIX. The distortion character of the LUMBERJACK

changes depending on your playing dynamics, ranging from a powerful clean

boost to subtle torn-speaker overdrive to gritty distortion. The LUMBERJACK is

housed in a durable, compact die-cast chassis, and includes true-bypass

switching to keep your bypassed tone intact.

- CONTROLS -

BOOST Knob – This knob controls the volume of your input signal. It can be

used to boost a quiet guitar, to achieve more distortion, or, when set to higher

settings, allows your natural guitar tone to blend with the overdriven signal.

LOG FACTOR Knob – This knob controls the amount of logarithmic distortion

created by the LUMBERJACK. As you turn LOG FACTOR clockwise, overdrive

distortion increases.

VOL Knob – Sets the output level of the LUMBERJACK.

FOOTSWITCH and LED – The Footswitch selects whether the LUMBERJACK is

engaged or in true bypass mode. When the effect is engaged, the LED is lit.

INPUT Jack – This ¼” jack is the audio input for the LUMBERJACK. The input

impedance is 1M.

AMP Jack – This ¼” jack is the audio output from the LUMBERJACK. The output

impedance is 100.

9V Power Jack – Plug the output of the supplied AC adapter into the 9V power

jack located at the top of the LUMBERJACK. The LUMBERJACK requires 100mA at

9VDC with a center negative plug. The LUMBERJACK accepts Boss/Ibanez style

AC Adapters.
