Featuring two buffered outputs, one with a custom designed isolating transformer, Orange is pretty confident that the Amp Detonator is the smallest active, fully functional, buffered ABY pedal on the market. What’s more, it’s the only active ABY switcher that can be powered by a 9V battery. The transformer output has been meticulously engineered to be as transparent as possible, whilst both outputs are buffered with a low noise, linear circuit. Drive any length of cable to your amps with no loss of clarity and switch silently between them. No more unnerving "thumps" for you or the sound guy. The Amp Detonator also has a push-button polarity switch to correct common phase issues between amplifiers, keeping the tone fat and full.
