ground buzz, 180° polarity reverse to phase-match amps, Compact and rugged

functionality. This assures the guitar signal is routed directly to the amp without any buffering,
loading or tone altering circuits.

troublesome ground loops. Once on, you can also ensure your two amps are properly in phase
using the 180º polarity reverse switch.

space is always at a premium. Furthermore, because it does not require powering to make it work,
it eliminates the need for batteries and space hungry power supplies.
