You may just find that the Fulltone True-Path ABY guitar switcher is the most tonally-transparent switcher you've ever used.

Fulltone packed the True-Path ABY with top-notch components to make sure that your tone sounds the same on the way out as it does on the way in. And to match your tastes, there's also a switchable JFET buffer on each channel to help drive long signal chains without losing tone. But the best part of the True-Path ABY's innovative design is that you'll never hear a "pop" through your amp when you're switching.

  • Top-notch electronics for tonally-transparent operation
  • Custom-designed photocells mean ultra-low resistance
  • Switchable JFET buffers for maximum flexibility

Top-notch electronics for tonally-transparent operation

Fulltone put a lot of thought and development into making the True-Path ABY the most transparent switcher possible, and went to great lengths to get the right components for the job. The True-Path ABY uses a custom-wound, nickel core 1:1 transformer that eliminates grounding issues safely while leaving your tone intact. And Fulltone spent over a year working with photocell developers to create an optocoupler with only 50-ohms of resistance - most other switchers have 300- to 300-ohms of resistance, and you can hear the difference. But most of the electronics in the True-Path ABY are there for one reason - to eliminate the "pop" sound when switching, for completely silent switching.

Custom-designed photocells mean ultra-low resistance

Sonically speaking, electrical resistance changes your signal's tone. Not always a bad thing when you're looking for an effect, but completely undesirable when you're just trying to pass your signal along. The only resistor your guitar's signal runs through in the True-Path ABY is the optocoupler, which Fulltone helped develop to be an ultra-low 50-ohms - way lower than the average 300-/400-ohm load in most switchers. So you'll hear the same tone coming out of the True-Path ABY as you sent into it.

Switchable JFET buffers for maximum flexibility

The True-Path ABY gives you switchable JFET buffers for each channel to give you flexibility in different applications. If you have to drive a long cable chain after the True-Path ABY, turn on the buffer to maintain your tone. Using fuzz pedals, or other effects that sound best with a high-impedance signal? Turn off the buffer, and you'll hear the richness of your fuzzes and distortions without excessive "fizziness" or harshness. No matter what your signal chain has in it, you can make it sound its best with the Fulltone True-Path ABY.
