Bass and drum levels can be adjusted for the perfect mix using the TRIO+'s Bass and Drums knobs. The TRIO+ also features a Simple Bass button lets you select between 3 bass line modes for busy or simple bass lines. Pushing the Band Creator‚Ñ¢ paradigm further, the TRIO+ also allows you to loop and custom sequence your looped guitar parts to create full songs on the fly. Press the TRIO+'s Looper footswitch to record a loop along with an unlimited number of overdubs. The Loop level can be individually controlled using the TRIO+'s Loop knob. Loops can be recorded by themselves, operating just like a traditional looper, or along with the band. You can also apply built-in effects to your guitar signal by enabling the TRIO+'s Guitar FX button, or connect your favorite effects to the TRIO+'s FX Send and FX Return jacks.
