Love my 2420 but the fretboard is really noisy when I bend. When I push my finger across the board to bend, it makes a loud, 'groaning' noise as the fretboard resists the movement of my finger across it. Of course, it is most noticeable and annoying when I'm playing acoustically, which I do often. My Squier strat is completely silent but this fretboard makes a lot of noise. Anybody else run into this? Any solutions to treating the fretboard?
