i got a new american strat last week and yes the neck is wondefully smooth. i was wondering in say a few years will the neck loose its "smoothness" and become dull. is there anyway i can prevent this from happening if it does
Loosing smoothness hmm, I doubt it. If its manufactured good, it should stay in decent shape for some time. But then again I havent had the same guitar for many many years, so thats just my 2 cents.
give the neck & strings and bridge (last longer-no rust etc) a good rub down after you play
