Since the original was also used as an advanced AB/Y box by many, it was found that ground loops could occur- never again with the KMA Machines Tyler Deluxe Frequency Splitter! Both SENDs are transformer coupled (with TRIAD Magnetics) to always deliver warm saturation, while avoiding ground-loops (internal slide-switched ground-lift). Both loops also have their own phase inversion switch (+/-) to get rid of potential, unwanted phase cancelation. The master phase-switch ensures consistently reliable interaction with your set filter frequency at all times, no matter if you either have a loop engaged or not. Finally, the LP-CUT and HP-CUT switches will now mute your loops when bypassed, which helps tidy up performances.
