I got my guitar second hand and noticed the frets were grooved, i mean worn away. I was told by a few people its ok, and than it gives it character. Is that right? the grooves are less that a millimetre.
Ive noticed that my 5th string, 13th fret has a different sound from the rest, it might just be me, but it seems more reverbed, is this common or my imagination?

Also - My wah pedal works considerable better when my guitar is set to bridge pick up, is this true of all wah's?
