Hoping someone with a little insight can help me. I'm installing the 2 way truss rod from the bottom or back of the neck. Is there a wrong way? The rod i'm using is this one: http://www.alliedlutherie.com/truss_rods.htm I'm not a physic's major, but it seems if it will go both ways, then there is nothing wrong with placing the round stock towards the fret board, contradicting every picture i've seen. Seems logical for a top install to use the flat stock up for gluing considerations, but what about from underneath? The reason i would want to do this is to keep the adjustment piece closer to the top because of totally bizarre shape of the head and string lock of this bass. The neck setup would require removal of the string lock to adjust it and thats not practical. The tuners are on the bridge giving way to an unusual head stock. Allied Luthiers, LMI and StewMac have all answered to keep the adjustment side away from fret board...but when asked why? They say just cause....... This is a very expensive project with tons of time spent, with no room to experiment. any takers?
