An ABY box that will fit anywhere and won't mess with your sound.

The True-Path Soft Touch ABY Switching Box 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.

Using the most advanced 4 opto switching system ever, yet also offering the purest signal. Fulltone developed their photocells over the last year with a rather patient optocoupler manufacturer, and the 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.

Each channel has switchable JFET Buffers to drive long lengths of cables without any tone loss. Want it clean & clear for Fuzztones? Fuzz pedals like to be hit with High impedance signal like your pickups produce. Buffers are Low Impedance, so if you are a Fuzz connoisseur you simply turn off the buffer on the ABY channel that goes to your Fuzzes.

Other ABY's say they're silent... but truth is they have a slight "thump" that becomes a loud "BOOM" when splitting say a Twin Reverb and Vintage Plexi Marshall.

Do not confuse this with a simple metal box and 2 switches that comprise 99% of the ABY's out there. Those sound ok UNTIL your signal chain reaches 20 feet or more... UNTIL you hit "Both" and the signal is loaded down to oblivion, or UNTIL you get electrocuted because of grounding issues due to the absence of an Isolation Transformer that the True-Path has!

And don't think that your tone is going to suck because you see the inside of the True-Path and think that your signal is going through a bunch of circuitry. No Audio signal passes through the switches or ANY of that circuity! Your signal is going through ONE RESISTOR in the True-Path (that's the optocoupler), or if you choose, it will go through a tone-full JFET unity gain buffer that is rich and sweet, and perhaps a custom wound Nickel-core Audio transformer (B channel only).

All that gadgetry in the True-Path is simply to light up those 4 optocoupler in a way that they don't POP when switching between amps...NONE of your guitar signal goes through that.

It's pure. It's True-Path. It's Fulltone.

        Comments about Fulltone Custom Shop True-Path Soft Touch ABY Switching Box:

        It's tough to drop this kind of dough on something that doesn't make your instrument sound like laser beams or Jimi Hendrix, but how this unit affects your sound depends on you: what kind of amps you have, how you set each of them and how you place them in relation to each other. The ABY box takes your signal and sends it to two places; either one at a time or both together, WITHOUT any signal loss. I was skeptical, but I am now a firm believer. The obvious use here would be sending a guitar signal to two different amps, say one tube and one solid state, and then switching between them depending on the song. As a bass player who uses lots of effects, I use the Fulltone ABY to send my signal to two different amps at the same time (one bass amp and one keyboard amp,) and the effect is astounding. I love the sound of all of my different amps. Now I can experiment with combining them. Rock on!
