Hey all, its a very minor problem but one i just have to sort out...for some reason, the volume knob on my stingray is wobbley, not loads just slightly, i'm just curious to how i can get rid of this wobble, tightening it somehow?

The ol wobbley knob Eh? Could be one or two things either the set screw for the knob is loose or the pot itself is loose. Either way an easy fix!

theres a little whole in the side of it, would the alan key that came with the bass fit in? and would that fix it? if not, how can i fix it?

Yep thats were a allen key goes. Tighten that up and you should be good to go. If not, loosen it all the way and remove the knob, under the knob will be a nut that secures the pot to the bass check and see if its loose and snug it up if it is.
