How often should I get an adjustment with a luthier (ie, truss, saddle, nut)? It's never been done on two of my electric guitars; one is 10 years old and the other is one, and for the past 5 months I've been practicing pretty hard on the older one.
Is an adjustment necessary after each string change or only after each gauge change? If the gauge can remain the same, how about if the material changes?--ie, can I switch between XL and EXP, both the same gauge?
Also, will my guitar have a significant improvement after visiting the luthier?
Thanks guys.
