hey guys i bought a new bass today and i dig its tone and all but it doesnt play as well as my old bass. The action at the 1st few frets and very nice but it gets kinda high ascending towards the last frets.... i brought it to a lutheir just now and the dude said the neck is a tad too straight and just play for a week or so and it'll settle down??? also, i tried raising the pickups to give more output. BUT one of the screwheads are kinda messed up(from repeated unscrewing maybe?) and i cannot unscrew it with a screwdriver....and i screwed?
