Active ABY Switcher

FTelettronica is an Italian one-man shop in Isola del Liri, founded in 2008. They build faithful clones of rare and discontinued effects, using Alpha pots, Neutrik/Lumberg jacks, and a 2-year warranty.

The Active ABY Switcher uses transformer-isolated outputs to eliminate ground loop hum when splitting signal between two amps. At 12mA draw and 368g in a 125x101mm enclosure, it's a solidly built routing solution. Currently out of stock, suggesting steady demand.

True transformer isolation is the right way to solve hum problems in multi-amp rigs. No workarounds, no compromise.
