The (LEE-La) 1at3 SGoS is a programmable true-bypass switcher that lets you switch backwards and forwards between up to three amplifiers, when you want, as often as you want. In combination with jack socket C→B, output C can also be used alternatively as an effect loop for amp B, excluding all the effects you don't currently need from the signal path. A tuner can also be connected to output A, taking it, too, out of the signal chain.
