I came across the DigiTech Trio purely by chance. I was scanning some of the product news coming out of this year’s NAMM and I saw a YouTube demo by Jason Zerbin. Jason is part of a Canadian indie band called Zerbin. I love their websiteÂ and their music. Definitely worth a look.
The Trio listens to your guitar and creates matching bass and drum parts. Jason’s video highlights how the pedal operates. Basically you press a footswitch to teach Trio the song part and then press it again to start playing with the drummer and bassist.
I’m not sure how well this pedal would work in a live situation. I don’t think the unit can store multiple songs for on-demand playback of backing tracks. However, for individual practice it looks like it would be a really dynamic tool for players.
