umm, yeah. i got home today after buying a bass off my mate for £30 something and sat down to see what needed sorting. i saw the strings were rediculasly high, so i had a look at the bridge, ok some crappy bridge. ( its some copy of and SG, 3/4 size ) so i looked around, saw the neck was a tad bent, and this was the problem with action, so i sat down will and sallen key and got poking. the lil adjuster for the truss rod was at the bottom of the fret board which was wierd, but i still had a lil go. tightened it a bit, saw no diference, and i did this a few times, (i know this was VERY VERY stupid after reading other posts like this ) then i herd a crack, and the truss rod just kept turning and made no difference and i could pull it out of the neck. so i though, not to abd of a problem, ( me being stupid ) so i tried screwwing it back, but id didnt work. NNOOOO so i sat there going bugger, ive just destroyed the bass. is there any way of fixing this, if so what and how much, better not be too much i spent £30 something on it in the first place.
