Electro-Harmonix EHX TORTION Instructions

EHX TORTION
JFET Overdrive/Preamp
Congratulations on your purchase of the EHX TORTION, the most advanced and
dynamic overdrive pedal on the market today. The EHX TORTION uses analog
JFET technology to reproduce the overdrive and distortion character of a tube
amplifier, all in a compact, durable die-cast chassis. Three-band EQ and a Pre-
Gain switch hone your sound, and a footswitchable BOOST mode adds a second
channel of modern high-gain tones.
WARNING: Your EHX TORTION comes equipped with an Electro-Harmonix 9.6DC-200BI
power supply (same as used by Boss ® & Ibanez ® : 9.6 Volts DC 200mA). The EHX
TORTION requires 27mA at 9VDC with a center negative plug. Using the wrong adapter
may damage your unit and void the warranty. The EHX TORTION also accepts 9V
batteries, we recommend alkaline.

- MODES OF OPERATION: NORMAL VS. BOOST -

The EHX TORTION operates in two modes: NORMAL and BOOST. The NORMAL
mode uses three JFET stages for low to medium gain sounds. The volume and
gain controls for NORMAL mode are located in the top row of knobs. The boost
mode is activated with the BOOST footswitch, and adds a fourth gain stage for
modern high-gain tones. The BOOST volume and gain knobs are on the bottom
row of the controls. The volume and gain controls for each mode are completely
independent, allowing the two modes to function like two separate channels on a
tube amplifier.

- CONTROLS -

GAIN Knob – The NORMAL GAIN knob is on the top row. This knob controls the
amount of input gain when the pedal is in NORMAL mode. This knob is disabled
when in BOOST mode.
PRE-GAIN Switch – This switch controls the level and tone of the initial input
signal to the EHX TORTION. This switch has four settings. The two leftmost
settings select a lower input level, for vintage plexi tones. The two rightmost
settings are higher gain for a modern, hot-rodded sound. Each pre-gain setting
has two tone selections: Full or Tight, indicated by F and T. The Full setting has
