uglycustard Posted March 6, 2012 Share Posted March 6, 2012 Hi folks, looking for a wee bit help with thomastik strings.I have a set on my backup bass a fender road worn jazz and cant seem to get a nice action with the jf344's the saddles are almost at the bottom and the truss-rod is full at clockwise.When you sight down neck I can see an up-bow,so i was wondering if a higher tension string would cure the problem and pull the neck up? Would be happy to hear some [font="arial, sans-serif"][size="2"][color="#000000"][b]opinions.[/b][/color][/size][/font] [font="arial, sans-serif"][size="2"][color="#000000"][b]cheers[/b][/color][/size][/font] steve Quote Link to comment Share on other sites More sharing options...
Legion Posted March 6, 2012 Share Posted March 6, 2012 (edited) I wrote a response but now I'm just confused all round. Is your truss rod screwed in fully clockwise? or did you mean unsrewed fully anit-clockwise? Edited March 6, 2012 by Legion Quote Link to comment Share on other sites More sharing options...
ikay Posted March 6, 2012 Share Posted March 6, 2012 If the truss rod is fully clockwise (not good if it's at the end of its travel!) then are you seeing a back-bow in the neck or an up-bow? Max tension in the rod would generally result in a slight back-bow and the strings would be 'grounding out' on the frets. If you're still getting an up-bow (ie. the neck has some relief) and you want less relief (ie. a flatter neck that will lower the action) then putting on higher tension strings will have the opposite effect to what you want Some pics might help.

uglycustard Posted March 7, 2012 Author Share Posted March 7, 2012 yep the rod screw is right in fully clockwise and it has an up bow ie the neck is bowed away from the strings Quote Link to comment Share on other sites More sharing options...
ikay Posted March 7, 2012 Share Posted March 7, 2012 This doesn't sound right at all. If you can post some pics it will be easier for people to see what's going on and offer help Quote Link to comment Share on other sites More sharing options...
mart Posted March 7, 2012 Share Posted March 7, 2012 [quote name='uglycustard' timestamp='1331135512' post='1568242'] yep the rod screw is right in fully clockwise and it has an up bow ie the neck is bowed away from the strings [/quote] TI strings have very low tension, so the only way this makes sense is if your truss rod tightens the opposite way to normal. Try screwing it anticlockwise and see if that helps. Quote Link to comment Share on other sites More sharing options...
uglycustard Posted March 7, 2012 Author Share Posted March 7, 2012 ok folks thanks for the help I'l give the idea of marts and try it anticlockwise cheers steve Quote Link to comment Share on other sites More sharing options...
BassBod Posted March 7, 2012 Share Posted March 7, 2012 Normally, I've found Thomastiks need to have the truss rod loosened a bit (not much at all, maybe a quarter turn?) and then I also move the bridge saddles up (again only a touch, maybe one turn) to compensate for the floppiness. After that they still need a gentle touch, but are very nice when you get used to the feel. Lovely sound. Quote Link to comment Share on other sites More sharing options...
Ou7shined Posted March 7, 2012 Share Posted March 7, 2012 I feel a discussion on the difference between tension and compliance coming on. Quote Link to comment Share on other sites More sharing options...

I find this thread most confusing. Lay the bass flat on a table, on its back. Now is the neck making a u- or a n-? u- to me (can I feel a song coming on?) is upbow which means the string pull is greater than the truss rod tension. Truss rod clockwise to correct (ie: Tighten truss rod) n = too tight, strings bottoming out on frets 5 - 10, loosen truss rod (anti-clockwise) as string tension is lower.
