I’m a Bassist Too

While playing, simply turn the SUB knob to dial in the polyphonic sub-octave level. It’s a quick way to add low-end weight and sonic depth to your loops.

A World of IR Tones at Your Fingertips

Loaded with 7 onboard IR presets covering classic guitar and bass cabinet sounds, Loop lets you instantly switch between styles.

Connect to your computer via USB to access the IR Manager software, where you can fine-tune the tone and load your own third-party IR files — create a sound that’s truly yours.

Loop It. Share It.

Loop supports USB audio and OTG functionality. Connect it to your phone or other mobile devices via the USB-C port to transmit high-quality digital audio for internal recording or sharing.

It features 24-bit/48kHz recording quality and up to 6 minutes of looping time, with unlimited overdubs–so you’ll never lose that flash of inspiration.

Auto Recording Made Simple

In addition to manual recording, you can switch to Auto Rec Mode by tapping the RECORDING MODE BUTTON/LIGHT. In this mode, recording begins automatically the moment you start playing — no need to stomp. Focus on your performance, not the footswitch.

Practice in Peace

Equipped with a 1/8” headphone jack, it can also function as a headphone amplifier. Place it at the end of your pedalboard and simply plug in your headphones–even without a speaker cabinet, the IR cabinet simulation delivers an authentic amp-like tone, making silent practice more enjoyable!

You can also connect your computer via USB-C to play backing tracks, making practice and songwriting more flexible and efficient.
