The BOSS RC-1 Loop Station's simple format gives you up to 12 minutes of a single loop to add interest and depth to your music. With mono and stereo connectivity, it gives you the flexibility you need to make full use of your stereo effects pedals and amplifiers, as well as synths and other instruments. A 24-segment LED indicator changes colors and rotation speeds depending on the status and mode you've got the pedal working in, so you'll never have to guess where you're at in the music. Looping novices and pro players at Sweetwater agree, the BOSS RC-1 Loop Station is one of the easiest looper pedals you'll ever use!
