so why switch to graph tech?
for me it's a matter of trying. the H1 Fender Strat is equipped with a set of vintage type saddles, which i dislike very much, as they feature protruding action adjustment screws that jab my palm all the time. the fact that they feature a polished surface design to reduce string breakage, is a bonus for me. for those who worry about having black saddles in a non-black guitar, then these saddles aren't for you...
the tonal difference is subtle, i hear more polished top end after the installation, which to me, is a welcomed change as it helps beef-up the lower end. fender purists will lament a loss in some Fender signature tone; this is the least of my worries- a good sounding Fender is a good sounding Fender, vintage or otherwise 8)
also, the current
American Series saddles feature an off-centre bridge end mounting which are the wrong saddles to get if your fender features a traditional version.
Kenny Wayne Sheppard (below) currently has the Graph Techs in his strat, in any case, we shouldn't be cued by Pros to consider using certain products. if it works for you, then you should embrace it.
