I purchased this a year ago. I've only used it a few times, so it's in excellent working condition. The following is quoted from Soundhouse: ■ Guitar Effects Pedal ■ Loop Station ■ Power: 9V battery or adapter PSA100 (sold separately) ■ Current consumption: 95mA ■ Dimensions, weight: 73W x 129D x 59Hmm, 440g ■ The simple design of the RC-1 makes it the perfect first looper. Recording, playback, overdubbing, and undo/redo operations are all done with a single pedal. In addition, the innovative circular loop indicator clearly displays the recording, playback, and overdub status and tempo. You can grasp the information you need for your performance at a glance, allowing for intuitive loop performance without getting lost in the operation. ■ The RC-1 has a maximum recording time of approximately 12 minutes in stereo. For example, you can perform with a full audio track as a backing track, allowing you to experiment with ideas as much as you like. ■ You can also connect effects with stereo output or instruments with stereo sources such as synthesizers for loop performance.
