1590B
From the vendor
Handy switch to select between two different outputs or both at the same time. ABYs are normally a PITA to wire up, but this board-mounted switch kit takes all the hard work out of it. Optional Klon Buffer on-board to keep your signal sparkling and healthy. Available in a few different box configurations, and you can have AB indicated by two different LEDs or a single two-colour fella. Please note: you may experience noise issues connecting two amps to this, you may not. If you want to avoid the possibility of any issues you'd have to go for a more complex (and expensive) transformer-isolated box. Kit includes: PCB, all components, footswtiches, hook-up wire, jack sockets, DC socket, LEDs. Enclosure (pre-drilled) is optional and won't take a battery. No knobs required. Difficulty: Easy PCB size: 85 x 21mm Footswtich spacing: 65mm Enclosure: 1590B If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability. Download INSTRUCTION PDF
