We are trying something new. If you are playing guitar, and use the trigger on the LEFT (Fret hand) CONTROLLER, it will lock both the left and right hand controllers to the guitar. You still move up and down the fretboard, and up and down the strings to strum, but your hands will stay locked to the guitar.
We think this will help you score better - let us know!
