FX Loop Pro is your fully integrated buffer, routing box, isolation and phase-control system, and summing/line-mixing device-all in one streamlined package.

Whether you use your tube amp’s FX Loop for 4- and 5-cable method, or love to test out new pedals, FX Loop Pro will streamline patching in external devices on your board in mono or stereo!

Don’t want to use your amp’s FX Loop for a gig? No problem—just don’t patch into the Dry and FX Send jacks. FX Loop Pro will auto-bypass those jacks and keep signal flowing at all times!

Now you have buffers in all the right places, no more noisy ground loops, and you can switch between mono, dual mono, 4-cable, 5-cable, and stereo without re-routing your entire pedalboard!
