Can I adjust the boost level on my VoiceLive Play GTX?
To adjust the boost level you need to plug in the Switch-3 foot controller and assign one of the buttons to Boost in the Switch-3 screen under setup. Then, you press the button when on the guitar effects screen. You’ll see Level and Drive get a (B) next to it. That’s your boost level.
Once it’s set, you save the preset and it’ll go back and forth between the regular and “boost” setting when you press the Switch-3 button.
