its solved now.. however im never goin back to that music shop because of sheer rudeness.
Took it into the shop, the truss had twice as much relief as needed (i refuse to touch the truss until im shown how sometime) also yes by some miracle i wrapped them the wrong way.
However they got really rude about the fact that i didnt buy the bass off them (altho i was paying for the work to be done

) and who can blame me for £100 difference
Then to top it off, i asked how much for a bridge and pickup to be fitted (quarter pounder and BAII) and they said are you buying them from us. Told them i wasnt and they just ignored me from then on and gave me evils.
