How to adjust the truss bar when putting on new strings on a lyons/washburn L115

I believe that guitar has the adjustment inside the sound hole toward the neck - it should take an allen wrench to adjust it - or it could be on the peg head between the tuners - anyway, to check the adjustment fret the first fret and the fourteenth fret and look at the distance between the string and the seventh fret - you want about a 32nd of an inch, called relief, so the neck is not straight, but has a slight bow in it - if you turn it clockwise you will reduce this distance - if you turn counter clockwise you will increase this distance - turn a little at a time - if you are not seeing a change stop and take it to a shop to be checked out - don't turn more then one turn if you are not seeing a change - hope this helps - have a nice day :O) I believe that guitar has the adjustment inside the sound hole toward the neck - it should take an allen wrench to adjust it - or it could be on the peg head between the tuners - anyway, to check the adjustment fret the first fret and the fourteenth fret and look at the distance between the string and the seventh fret - you want about a 32nd of an inch, called relief, so the neck is not straight, but has a slight bow in it - if you turn it clockwise you will reduce this distance - if you turn counter clockwise you will increase this distance - turn a little at a time - if you are not seeing a change stop and take it to a shop to be checked out - don't turn more then one turn if you are not seeing a change - hope this helps - have a nice day :O)
