The EHX TriParallel Mixer is a powerful effects creation and mixing hub with three separate FX loops and flexible controls allow for multiple configurations. The Tri Parallel Mixer is surprisingly compact considering the level of functionality it provides, while its intuitive controls and I/O make it easy to operate. Use it to switch between or mix up to three separate effects loops. Send a guitar or other instrument out to three separate amplifiers, or input three separate instruments to switch between or mix to a single output. Mix effects in parallel to create sounds and allow for options not possible when using effects in series (one after another).
