Want to play a short guitar phrase, hear it repeat, then add another part? The BOSS RC-1 records your instrument’s audio and loops it through your amp. Choose it when the backing part should come from what you just played, rather than a prerecorded track or a computer-generated instrument. You still need suitable instrument cables and an amp or monitor.

Red BOSS RC-1 Loop Station with LEVEL knob, circular loop indicator and footswitch — This guide covers one red RC-1, not an RC-30 or an accessory bundle.

Your playing becomes the backing part

For an electric guitarist who already has an amp, the appeal is immediate: capture a chord phrase, let it repeat, and play a melody over it. Overdubbing lets you record another layer onto that loop. The RC-1 handles the captured audio itself, so this job does not require computer recording software.

That is a different purchase from a MIDI keyboard that sends notes to software, a foot controller that triggers app commands, or a metronome that supplies a click. If you want to build and edit a collection of songs on a computer, choose a recording workflow designed for that job instead.

RC-1 staged beside an amplifier, other pedals and loose instrument cables — Manufacturer staging, not a demonstrated hookup. The amp, other pedals and cables are separate equipment.

BOSS specifies approximately 12 minutes of maximum stereo recording time. That is the recording limit, not battery life or a limit on how long a short phrase can repeat. The latest recorded phrase remains after power-off; do not treat that as a library of separately saved songs.

Separate close-up photo of the RC-1 with its loop indicator illuminated — The illuminated ring shows loop status. LEVEL controls the recorded loop’s playback volume, not the incoming instrument level.

The circular indicator gives a visual reference for recording, playback and overdubbing. The LEVEL knob adjusts the loop’s playback volume so you can set it alongside your live part. This is not a claim that the pedal will improve your timing or that every action takes a single tap; read the supplied operating instructions.

Follow the audio to the amp

A basic mono setup needs an audio cable from the instrument to the pedal and another from the pedal to the amp. The RC-1 uses quarter-inch audio inputs and outputs; match the cables and signal requirements to your actual instrument and listening equipment. It has no built-in speaker, Bluetooth listening connection or direct headphone output.

Do not buy it for USB recording. Although the retailer’s hardware-interface field says USB, BOSS’s connector list and manual identify audio, power and external-control jacks, with no USB port. It is not a USB audio interface or a computer-powered pedal.

RC-1 with four cables attached to its two audio inputs and two audio outputs — Four cables illustrate stereo audio connections, not four separate loop tracks. Cables are not promised with this single-pedal selection.

The paired inputs and outputs support stereo setups, but stereo requires suitable equipment on both sides. The four-cable photo illustrates those physical connections; a single guitar and amp can use the documented mono path. Follow the manual’s connection and power-on precautions rather than copying a staged photo.

Order the pedal, plan the power separately

The RC-1 runs on a 9V alkaline battery or the separately sold BOSS PSA-series adapter; BOSS specifies a 95 mA current draw. This is not a USB charging arrangement. If you want outlet power, choose the specified adapter for your local supply rather than assuming any 9V adapter will do.

The linked selection is RC-1 / Loop Station Guitar Pedal, red, one pedal. An optional external footswitch and AC adapter are separate purchases, and the product scenes do not make the amp, other pedals or audio cables part of the box. Choose this RC-1 for repeating and layering your own instrument phrase through an appropriate audio setup.
