Description

Edit description

Introduce a new dimension to your sound with the Electro-Harmonix Tri Parallel Mixer, a dynamic and versatile tool for every musician. This innovative device enables a unique mixing experience by allowing up to three separate FX loops to run in parallel, creating a sonic palette that's impossible to achieve with traditional series-connected effects.

With the Tri Parallel Mixer, you can seamlessly switch between FX loops in XOR mode, send a single instrument out to three separate amplifiers, or mix three instruments into a single output. All this power is packed into a compact, easy-to-operate unit that won't crowd your pedalboard.

This device not only gives you the freedom to experiment with your sound but also ensures your effects play nicely together. Each channel comes with its own independent send and return volumes, EQ, and phase controls, allowing you to fine-tune your sound to perfection.

And for those who crave a touch of the original, the global Dry Volume knob lets you blend in your untouched signal for a more nuanced tone. Whether you're a guitarist looking to layer effects without compromising feel or a bassist wanting to keep your low-end clarity, the Tri Parallel Mixer is your ticket to sonic exploration.

Key Features:

Three separate FX loops for parallel running
Seamless switching between FX loops in XOR mode
Ability to send one instrument out to three separate amplifiers
Capability to mix three instruments into a single output
Independent send and return volumes, EQ, and phase controls for each channel
Dry volume knob for blending in the untouched signal
Compact and easy-to-use design
Comes with an EHX 9.6DC power supply

Critic Reviews

EHX Tri-Parallel Mixer Review | TalkBass.com

talkbass.com

The Electro-Harmonix Tri Parallel Mixer is a game changer for bassists, tackling common issues with pedal setups by allowing three effects loops and a blend of direct signal for better tone integrity. While it excels in flexibility and ease of use, particularly in live settings, it falls short with distortion effects, lacking depth and bottom end. Despite this drawback, users rave about its ability to enhance sound without sacrificing fundamentals, making it a highly recommended addition to any pedalboard, albeit one that comes with a complex array of controls.
