★Listing ends on Friday, October 24th. This is a 4-loop switcher from EXECTIVE SOUND (currently Lagoon Sound), with 2 loops + A/B selector. It does not have a program function. The upper right and upper left loops can be turned ON/OFF individually, and the lower right and lower left loops are switched with the middle switch. It's a simple design. It uses a 9P 3PDT true bypass switch and is very well-built. It runs on 9VDC and can also use batteries if you open the back cover. There is a slightly large scratch on the surface, but it functions without any problems. The item for sale is the main unit only.
