Hi everyone, I'm a guitar player but recently I purchased a Washburn XB100 Bantam Series Bass for recording and messing around on. I've had it a few weeks and thought the setup was pretty nice, so no worries there. That is until I attempted to change strings today. All I did was take the old strings off, didn't adjust anything on the bridge etc. When I went to put the new strings on the whole action seemed to have changed(they are the same gauge strings I took off) with buzzing on bunch of the frets, making it unplayable. I've read a couple of articles on adjusting the action and went ahead and heightened the saddles, but all this has done is make the action extremely high on the high up frets. Sorry if I sound nieve here but like I say I am a new bass owner - there are 3 screws right above the fretboard on the headstock, is this the equivalent of the truss rod? Should I adjust these screws? Here's a pic of what my bass looks like if that helps:- http://www.shop-sotw.com/Merchant2/...B100&Category_Code=BGUITAR&Store_Code=STRINGS I'm finding this quite frustrating a I just want a reasonably low, even action with no buzzing. I'm hoping you guys can help me out.
