EXECUTIVE SOUND (formerly LAGOON SOUND) Loop Switcher AB Selector Handmade effector/selector workshop LAGOON SOUND's product from when they were still using their old company name. This unit combines an AB selector, output selector, and mute switch. I removed it from my pedalboard when I changed my system. I tried to cleanly remove the Velcro on the back of the case once, but the paint also came off, so I gave up and reapplied ONE CONTROL Velcro. I am selling it to organize my equipment. Operation confirmed. Please judge the condition from the photos. Shipping via Yu-Packet Plus.
