This is the Digitech TRIO, a groundbreaking pedal that can listen to your guitar playing, and then automatically generate musically appropriate drum and bass parts, providing you with an instant backing band for songwriting, rehearsals, or even solo gigs. The TRIO can learn up to three different parts for each song you teach it, with seven different musical genres and twelve selectable styles available for each genre. Instantly accessible half-time or double-time versions of your song are available via the Alt Time button, while a dedicated Tempo knob lets you vary the tempo continuously with no detriment to audio quality. The TRIO has auto-sensing outputs for plugging it into a guitar amp or mixer, onboard speaker emulation and guitar effects, and a headphone jack for silent rocking. Individual bass and drum level controls let you get the ideal rhythm section mix, and a control input lets you use an optional Digitech FS3X Footswitch for hands-free control of your virtual backup band. The Digitech TRIO is housed in a compact, rugged enclosure that can be easily integrated into any pedalboard, and it includes a dedicated 9v power supply.
