I have a mexican strat from 2000 or so, this guitar is a gem, it will never leave my side (its a mexi i know but it has become my favorite guitar). The volume pot is scratchy now, i mean you can move the thing with out it scratching, also I have to leave it at ten because it jumps in volume as your roll it up and down. And now my tremelo bar wont stay in, I think i striped the saddel... because no trem bar will stay in. Im thinking i want to just upgrade all the hardware... tunners and saddels vol and tone pots. Whats some great stuff at a decent price. Im looking callaham parts. Eventually i want to upgrade pickups as well. And recomendations. And are pots really easy to solder and instal?
