Pre owned ABY-ST pedal.

The ABY-ST (soft touch) has silent soft switches.

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.
