Hello! I just got done stripping and refurbishing my aunt's old bass, a hand me down for a project of mine. This is my first time handling a bass, or setting up one, I was very excited to. Anyhow, while installing the new strings for my bass, and attempting to set up my bridge, I noticed this long, small Black Crack that goes from the A string, down past the E string. What would y'all suggest I do? I've already loosened the strings. Would this be an issue with the trust rod inside? I didn't set that up. Maybe it could be because the wood is old, and was pretty banged up by my aunt before giving it to me, and it just let loose? In hind-sight, should of waited until tomorrow to bring it to a shop for set up so they can properly teach me, this thing is from 1980 after all. I was just super excited to teach myself how to string! Also, I wanted to show y'all what it looks like too! I'm very proud of the work I did on the front! Dark souls inspired engraving. Art was by me! Engraving by my grandpa.
