OK, Bought a Warwick RockBass Corvette SE 4 string (i know, save the flames) about a year ago, and i'm having big problems keeping the neck/action in line. We set it up, and it plays great for about a week or two, then the strings are way up again. I know its bad to keep adjusting the neck. I'm thinking the problem is that i run 5-string sets with the high string removed. i.e. too much tension. but i run these big strings because i tune to C# F# B E (# is the sharp symbol right?) My guitar players dad is very experienced in setting up guitars and basses and he is kinda vexed as to what the problem is with it, and im worried that eventually i will run out of trussrod and ruin the neck. I really like the sound of the large strings with the low tuning, so im not sure what i should do. I beseech the gods of TB to help me... How can i get the neck to stabilize with my big strings?
