BRIDGE
User Manual
Overdrive | Distortion | Fuzz

Welcome to the Electro-Harmonix Triboro Bridge,
a compact pedal featuring three unique saturation
algorithms: overdrive, distortion, and fuzz. The
overdrive is based on the algorithm featured in the
EHX Platform Stereo Compressor, the fuzz is based
on the algorithm featured in the EHX Attack
Decay, and the distortion is a new algorithm
unique to the Triboro Bridge.
Operating Instructions
Insert the output plug from the supplied 9VDC AC
adapter into the power jack at the top of the Triboro
Bridge. The unit must be powered to pass signal,
even in bypass. The Triboro Bridge features buffered
analog bypass. Connect an instrument cable from
your instrument to the Input jack. Connect an
instrument cable between the Output jack and a
suitable amplifier. Click the footswitch to engage
the Triboro Bridge and light the LED.

Power Suppy Requirements: Voltage: 9VDC Current: 100mA Polarity: Center-Negative
This device comes equipped with an Electro-Harmonix 9.6DC-200 power supply. Use of the wrong adapter or a
plug with the wrong polarity may damage the device and void the warranty. Do not exceed 10.5VDC on the power
plug. Power supplies rated for less than 100mA may cause the device to act unreliably.

Controls & Jacks
1. VOL Controls the output volume.
2. GAIN Controls the amount of saturation.
Note: when Gain is maxed out in fuzz mode, the
Triboro Bridge will make a lot of noise when you’re
not playing. Either activate the Gate knob or dial
back the Gain knob.
3. BASS/GATE In overdrive and distortion modes,
this knob is a bass control, allowing you to boost
or cut low frequencies. In fuzz mode, this knob
controls the threshold of a noise gate.
Note: when first switching to fuzz mode from a dif-
ferent mode, the gate is initially deactivated until
you move this knob.
4. TREBLE/TONE In overdrive and distortion
modes, this knob allows you to boost or cut high
frequencies. In fuzz mode, this knob controls the
cutoff frequency of a resonant low-pass filter.
5. TYPE Button Press this button to choose
your saturation mode:
Green – OVERDRIVE
Orange – DISTORTION
Red – FUZZ
6. Footswitch and Status LED Footswitch
engages or bypasses the effect. The LED color
indicates the selected distortion type. In bypass,
the LED is off.
7. Input Jack Impedance: 2.2MΩ, Max In: +1.5 dBu
8. Output Jack Impedance: 680Ω, Max Out: +2.1 dBu
9. Power Jack Current draw: 100mA at 9.0VDC
Input Contour Mode
By default, your guitar signal is unaffected before
being fed into the Triboro Bridge’s distortion algo-
rithms. An optional Contour EQ may be enabled
which cuts bass and boosts mids on the input
signal, producing a more modern character. To
enable Contour EQ:
1. Press and hold the TYPE button.
2. After two seconds, the LED quickly blinks 8
times indicating Contour EQ is enabled.
3. Release the TYPE button.
4. Repeat this procedure to disable Contour EQ.
Four slow LED blinks indicate Contour EQ is
disabled.
The Contour EQ setting is remembered through
power-cycles so you can set it and forget it.
