The Micro A/B is one of our best selling models. Extremely small, convenient, inexpensive, it's ideal for cluttered pedal boards. It works well to switch between two amps, and also works well as a Tuner Mute.
The Micro A/B uses the "S" enclosure. It measures 1.5 x 3.6 x 1.1 inches; 3.3 x 8.9 x 2.5 cm.
