Its a well-known fact that running two amps is not only enormous fun, but also a time-honoured way of achieving bigger tones on stage and in the studio. Whether its switching between two different amplifiers for their individual characteristics (rhythm and lead, for example) or using them simultaneously for huge walls of sound, pros have been employing this setup for decades. Achieving this easily, however, has always been a problem for guitar players. Poor quality passive ABY boxes/line selectors load the guitar signal down, degrading the tone and rendering the whole exercise almost pointless. Not to mention ground hum issues caused by non-isolated outputs. On the other hand, active ABY pedals are in short supply and are usually quite cumbersome. Driving long cables is no problem as the Amp Detonators buffered low impedance signal ensures your inputs upper frequencies are maintained. Output B features an isolating transformer which eliminates common ground loop hum when using two amps simultaneously. The transformer output has been engineered for maximum transparency, correcting some of the tone-altering characteristics that affect many other ABY boxes.
