Pitch Accuracy
Let's take a look at some ways to improve our bending tuning accuracy.
Exercise no.1: Check your math! If you're bending up on the B string, play the desired pitch on the high E string to check the bend is in tune. EX: Whole step bend from B string 15th fret, play E string 12th fret to check tuning.
Pro tip: Practice bending on one guitar and really learn the tension on each string. This will help you master control!
Exercise no.2: "Pre-bending" Start by bending the note up to the desired pitch, and then attack the string so you can hear the note. Check your math. Are you sharp? flat? adjust accordingly!
