more bass for a bigger sound. The Tight setting focuses the bass frequencies for
a more modern tone.
BASS Knob – Controls the level of the bass frequency range.
MID Knob – Controls the level of the middle frequency range.
TREBLE Knob – Controls the level of the treble frequency range.
VOL Knob – The NORMAL VOL knob is on the top row. This knob controls the
output level of the EHX TORTION when in NORMAL mode. This knob is disabled
when in BOOST mode.
BOOST GAIN Knob – The BOOST GAIN knob is on the bottom row. This knob
controls the amount of input gain when the pedal is in BOOST mode. This knob
is completely independent from the NORMAL GAIN knob, and is disabled when in
Normal mode.
BOOST VOL Knob – The BOOST VOL knob is on the bottom row. This knob
controls the output level of the EHX TORTION when in BOOST mode. This knob
is completely independent from the NORMAL VOL knob, and is disabled when in
Normal mode.
BYPASS Footswitch and red LED – This footswitch selects whether the EHX
TORTION is engaged or in buffered bypass mode. When the effect is engaged,
the red LED will be lit.
BOOST Footswitch and blue LED – This footswitch toggles Boost mode on
and off. When in Boost mode, the blue LED will be lit.
INPUT Jack – This ¼" jack is the audio input for the EHX TORTION. The input
impedance is 1M.
OUTPUT Jack – This ¼" jack is the audio output from the EHX TORTION. The
output impedance depends on the VOLUME setting, ranging from 250 to 25k.
BOOST SW Jack – Allows an external momentary footswitch to control toggling
Boost mode on and off. The external switch should be normally open. Upon
engaging the switch, it should create a short circuit between the Tip and Sleeve
of the plug inserted into the BOOST SW jack on the EHX TORTION. Releasing
the switch should open the circuit between the Tip and Sleeve. The BOOST SW
jack is connected in parallel with the BOOST Footswitch so they can both work at
the same time. A suggested momentary footswitch that has been tested with the
EHX TORTION is the Boss FS-5U Momentary Foot Switch.
