Fulltone True-Path ABY-ST V2 Switcher Pedal
The Fulltone True-Path ABY V2 has silent soft switches thanks to a Nickel core custom-wound 1:1 transformer that doesn't boost the treble frequencies, so fuzz pedals played through the True-Path sound round and distortions don't sound strident.
Using the most advanced 4 opto switching system ever, yet also offering the purest signal. Each channel has switchable JFET Buffers to drive long lengths of cables without any tone loss and can be turned off for use with low impedance fuzzes.
The True-Path also has a phase switch for in or out of phase signals and an isolation transformer to avoid noise and grounding issues.
