One Control Minimal Series 1 Loop Box

Effects Loop Switcher, A/B Box, or Input Selector

The One Control Minimal Series 1 Loop Box is a compact, durable, and versatile Effects Loop Switcher, A/B Box, or Input Selector. It enables true bypass switching to keep your tone clear while allowing you to toggle pedals, switch between amps, or mute your signal. Powered passively for switching and requiring a 9V adapter ONLY for the LED indicator, it fits neatly on pedalboards without sacrificing functionality or quality. Perfect for maintaining control of your tone and simplifying your signal chain.

You can use the 1 Loop Box in various ways – when the footswitch is OFF, the signal from the input goes directly to the OUTPUT. When the footswitch is ON, the signal from the INPUT is sent to the SEND jack, and the signal from the RETURN jack is sent to the OUTPUT. To keep your signal pure, the One Control Minimal Series 1 Loop Box uses true bypass switching with a high-quality mechanical footswitch.

When using the 1LoopBOX as an effects loop, you can turn on/off multiple effects pedals at once. Most importantly, for vintage effects units that may degrade the sound in bypass mode, use the 1LoopBOX to keep them out of your signal chain when not in use to help keep your tone pristine.

Using only the INPUT, SEND, and OUTPUT terminals will make the 1LoopBOX into an A/B box – by stepping on the footswitch, the output will be switched between SEND and OUTPUT jacks, enabling either a tuner out or switching between amplifiers.

Using only the INPUT, RETURN, and OUTPUT jacks, the 1LoopBOX can be an easy solution for an input selector. Connect instruments to the INPUT and RETURN jacks, and switch between them with the footswitch to have them appear at the OUTPUT.

If used with only INPUT and OUTPUT jacks, the pedal acts as a MUTE switch. Step on the footswitch to stop all signal and step on it again to resume the signal.

One Control Minimal Series 1LoopBOX uses a passive circuit, so there is no need for a power supply to control switching functions. However, the LED light does require power to operate for greater visibility. A standard center negative DC 9V adapter (EPA-2000 recommended) is required to display the ON/OFF status with the LED indicator. Batteries cannot be used.
