stu_g Posted January 22, 2012 Share Posted January 22, 2012 i have a hohner b2a bass which i have had for a while and have tried setting it up but it appears to have a slight backward bend in the neck ?the truss rod works but as this is for forward bows in the neck is of no use! i also have a hohner jack which i set up no probs from that ,is there anything i can do to fix it as now i have the jack i would like to sell the b2a but dont want to palm a dodgy bass off to anyone Quote Link to comment Share on other sites More sharing options...
franzbassist Posted January 22, 2012 Share Posted January 22, 2012 (edited) Is the truss rod as loose as it'll go? If not, loosen it (initially, no more than a 1/8 to 1/4 turn at most) and it should release the tension in the neck and remove the back bow. If it is as loose as can be adjusted, the bass needs some work Edited January 22, 2012 by walbassist Quote Link to comment Share on other sites More sharing options...
warwickhunt Posted January 22, 2012 Share Posted January 22, 2012 Slacken the truss rod right off and string tension should pull it forward, if that fails then with no tension on the neck you may need to apply pressure to the neck to bend it into a concave arc and then get the strings up to tension (probably best with the help of a friend). Failing that it is a luthier job to look at resetting the neck, possibly removing the fingerboard... probably not cost effective on a bass such as this!

icastle Posted January 22, 2012 Share Posted January 22, 2012 The remedy is really dependant on the degree of bow. If it's not too badly bowed then slackening of the truss rod, sticking a cheapy set of heavy bass strings on it and overtuning it is a good start - given a couple of weeks it'll probably pull itself back into the right shape. If the bow is very pronounced then you're looking at heating pads, g clamps, blosks of wood and several weeks worth of tensioning the whole assembly every day.

stu_g Posted January 22, 2012 Author Share Posted January 22, 2012 hi thanks for the replies its a very slight bow but obviously affects the setup will overtighten strings and leave it for a while cant do any harm and nothing to lose cheers Quote Link to comment Share on other sites More sharing options...
