Does anyone else have this problem? Often when I do a pull off on the high E string, I wind up pulling the darn string right off the fretboard. Not a good sound by the way. It's gotten to the point where I have to slightly bend the string up on the original note. It's worse when I'm attempting a fast triplet (for example I plant my index finger on the 5th fret, then pull the 8th fret, then the 7th fret. It seems to happen on all my guitars, so I don't think that it's a setup thing. Any suggestions?
