Frequently Asked Questions - Triboro Bridge Electro Harmonix

How do I switch between overdrive, distortion, and fuzz modes?

Press the TYPE button repeatedly. The LED color indicates the mode: green for overdrive, orange for distortion, red for fuzz.

What is the Contour EQ and how do I enable it?

The Contour EQ cuts bass and boosts mids on the input signal for a more modern character. To enable, press and hold the TYPE button for two seconds until the LED blinks quickly eight times. Repeat to disable (four slow blinks). The setting is saved through power cycles.

How does the BASS/GATE knob work in fuzz mode?

In fuzz mode, the BASS/GATE knob controls the threshold of a noise gate. Turn clockwise to increase the gate threshold. Note: the gate is initially deactivated when first switching to fuzz mode until you move this knob.

What does the TREBLE/TONE knob do in fuzz mode?

In fuzz mode, the TREBLE/TONE knob controls the cutoff frequency of a resonant low-pass filter. Turning clockwise raises the cutoff, making the sound brighter.

What power supply should I use?

Use a 9VDC center-negative power supply rated for at least 100mA. The included Electro-Harmonix 9.6DC-200 adapter is recommended. Do not exceed 10.5VDC or use the wrong polarity.

Is the Triboro Bridge true bypass?

No, it features buffered analog bypass. The effect is engaged when the footswitch is pressed and the LED is on. In bypass, the LED is off but the unit still needs power to pass signal.

What are the input and output specs?

Input impedance: 2.2MΩ, max input: +1.5 dBu. Output impedance: 680Ω, max output: +2.1 dBu.

Why is there loud noise in fuzz mode when I'm not playing?

With the Gain maxed in fuzz mode, noise is normal. Activate the gate by turning the BASS/GATE knob clockwise, or reduce the Gain knob.

Can I use this pedal with bass guitar?

Yes, the pedal works with bass. In overdrive/distortion modes, the BASS knob allows low-frequency adjustment. In fuzz mode, the gate can help control noise.

How do I ask a question or get support?

USER MANUAL Triboro Bridge Electro Harmonix

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 Supply 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 different 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

1. Footswitch and Status LED Footswitch engages or bypasses the effect. The LED color indicates the selected distortion type. In bypass, the LED is off.
2. Input Jack Impedance: 2.2MΩ, Max In: +1.5 dBu
3. Output Jack Impedance: 680Ω, Max Out: +2.1 dBu
4. 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 algorithms. 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.
