The 1 Loooper is one of our best selling models. Small, convenient, inexpensive, it's ideal for cluttered pedal boards. It works well in a situation in which you want to bypass maybe just one or two pedals with one stomp (or even several pedals).
The 1 Loooper uses the "B" size enclosure. It measures 4.4 x 2.4 x 1.0 inches; 11.3 x 6.1 x 2.5 cm.
