Electro-Harmonix LUMBERJACK Manual

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 1MΩ.
AMP Jack – This ¼" jack is the audio output from the LUMBERJACK. The output
impedance is 100Ω.
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.
