Is this for you?

Yes if you run a V3 Creation board, want a single place for your inputs and outputs, and you want to buffer and isolate your signal.

No if you're not on a Creation V3 board. This mounts to Creation V3 boards. Look at LongLine, the Interfacer or Audition instead.

CMC Hi/Lo io with galvanic isolation on the right output for a dead quiet signal

Dead quiet signal

Comes with galvanic isolation on the right output to kill the noise from ground loops and fix out of polarity amps.

Buffered your way

Input and output buffers keep your signal intact. Bypass the input buffer when using impedance-sensitive fuzz or vintage pedals.

FAQ

Will it fit my board?
Mounts to Creation V3 pedalboards, custom shop included. If you're not on a Creation board, you can mount Hi/Lo io to your pedalboard as you would any other junction: hard mount it with screws, or use Dual Lock or Velcro to attach it to your board. We also have LongLine, the TX Interfacer and many other junctions to consider if you're not on a Creation V3 board.
Hi/Lo io vs FX Loop Pro?
Hi/Lo is buffering, isolation, summing and phase. If you also run 4 cable method or need to audition pedals, go with FX Loop Pro.
What routing options do I have? Mono? Stereo?
You can run multiple rig types with Hi/Lo. Mono, dual mono, stereo and wet dry are the main options. You can also access its extra hidden outputs to run tube amps and amp sims at the same time.
How do I access Hi/Lo's hidden outputs?
The Left and Right inputs are actually TRS jacks. The tip of the TRS jack carries signal as you'd expect, to the Left and Right outputs as normal (use a standard TS cable here for normal use). If you want to access the duplicate outputs, use an Insert cable (TRS to dual mono cable) on the left and/or right input. Now the ring of the L and R input becomes an output you can send to amp sims or other amps via LongLine or another patch bay or pedal. See manual for more details. Note: these extra outputs are buffered but they are not affected by the ground lift or phase pushbuttons.
Will it kill ground loops?
If the noise is a ground loop or polarity issue, yes. The right output of Hi/Lo is isolated with a transformer (you can lift the ground and invert polarity on this output with the onboard pushbuttons). If it's a failing power supply or a noisy pedal, that's a different problem, email us and we'll help you trace it.
