Fulltone True-Path ABY-ST Pedal
One has silent soft switches... that's the "ST" (Soft Touch). One has a Hard click in the switch (only for the driver's feel & not evident through the amp)... the "HT" (Hard Touch). No pops, no ticks, and no electrocutions, thanks to a Nickel core custom-wound 1:1 transformer that doesn't boost the treble frequencies like the "industry standard" Jensen transformer does, so fuzzes played through the True-Path sound round and distortions don't sound strident. I can hear it, so can you.
Using the most advanced 4 opto switching system ever, yet also offering the purest signal. I developed our photocells over the last year with a rather patient optocoupler manufacturer (Thanks Fred), and my cells only have around only 50 ohms series resistance compared to the Vactecs (which all other optocoupler switchers use) offering a whopping 300-400 ohms of series resistance to your guitar's signal. I can hear 300 ohms... you can hear 300-400 ohms.
