Good day tgp! I have a thomson hummingbird copy that currently has 12 gauge strings on it. Im tuned to e standard. I plan to drop it to D standard and was hoping to have it set up for 14 gauge strings. However, my friend has warned me against going to 14's right away; even if I tune a whole step lower, it might be a too big jump from 12s. He suggested that I try 13's first. Is that true? It'd save me a set of strings and a few weeks if I go for 14's right away. I'd also like to note that the area around the bridge has been in a permanent bulge since I got the guitar. It has since been setup, but the bulge remains. Is that gonna be a problem? Thanks!
