The Morley ABY Mix guitar mixer and switcher routes 1 signal to 2 inputs or 2 inputs to 1 output. So you're at a gig, with your electric and acoustic-electric guitars, but only have a single amp. You want to be able to jump between the electric and acoustic-electric guitars, but you hate the constant cord-changing and the loud pops you get when doing so. <br /> <br />The Morley ABY Mix pedal tackles this obstacle so you can get back to doing what you love-rocking out on your axes. The Morley ABY Mix pedal lets you choose A, B, or A and B combined for mixing two different instruments. Two bright LEDs show you which signal is active. The unit is true bypass and passive, so it will work without a battery (a 9V battery is required for the LED to function). Designed with a cold rolled steel housing, this rugged pedal will stand up to the rigors of the road, or wherever you need a quick instrument change on-the-fly. Warning: Do not use on powered speaker lines. You will damage your amp, speakers, or both. <br /> <br />Morley pedals are designed for musicians who want more than just the same old pedals built the same old way. This pedal contain innovative designs, clever features, and bullet-proof construction. Each and every one is hand-assembled in the U.S.A. with American-made pride.
