The BigShot ABY is a true bypass amp selector that allows you to play two amplifiers from one guitar and toggle between the amps or play both at the same time. Because it is 100% passive there is no buffer and therefore, no need for powering or batteries. This also means that it does not impart any tonal change when performing basic A-B switching between amplifiers. To add versatility, the BigShot ABY is equipped with an isolation transformer and 180º polarity reverse on output B. These features combine to provide a means for a guitarist to connect two ‘incompatible’ amplifiers together that would otherwise cause hum and noise due to grounding issues. When used after a buffered signal, the effect of the transformer is minimal. When used without a pre-buffered signal, the player compensates on amp B for any perceived tonal shift caused by the transformer. The transformer may be switched out of the signal path for amp setups without grounding issues. A ground lift is also provided as a means to further suppress noise caused by ground loops. For even greater connection ease, a separate tuner-out jack is provided that is common to the input.
