Endorsements & Reviews

"The ATG-1 Pedal is amazing, and the pickup modeling is the most accurate I've experienced - and I own them all. (Roland VG-8, VG-88, VG-99, GR-55, Boss GP-10, Line-6 Variax, Tyler Variax JTV). It has breathtaking clarity, totally pro, highest dynamic range - no need for a "N.S." Noise Suppressor as required for many of the Roland Boss COSM Guitar Models."

Steve Conrad (Elantric), founder/moderator of

“The ATG Auto Tune System is unlike any other. It’s intuitive to players’ idiosyncrasies and offers stunning intonation within a vast amount of instant tuning potentials and variety of eclectic guitar modelings. It aids the player in walking that bridge to being tuned up, turned on and tapped into their infinite, unique creativity. It helps me to sound as good as some people think I am.”
