A buddy of mine has a Highway One Strat and just can't get a good sound out of it. I think it may be the pickups. Lots of treble - very harsh sound. Does anyone know what kind of pickups are in these? Any opinions/experience? Is it worth putting a new set in? He's mainly the singer in the band playing backup so I don't know how much money he'll want to sink into it. Thanks - Al Z.
