What do they usually charge you? I'm talking things like set-ups, pickup swaps, and other general work, etc.
I've never used a tech other than this one cool old dude that Shannon introduced me to who you have to pretty much force money into his hand. Even then, it's only been for stuff that I just don't have the tools for.
I've always kind of played around with the thought of doing tech work as a little side job but never really new what to charge. I get tons of compliments on how my guitars play and requests to set up theirs but I usually just turn them down.
Depends on the person really, I know a guy that does pretty good work for a low rate.
Like he's putting in a 5 way switch and re-wiring pickups that aren't giving enough power for like 30$, he even picks the guitar up and takes it home, then will meet you to give it back. He's done work for Metallica, Eric Johnson, and some other cool people as well.
Great guy. It really depends on you though.
I'm sure someone could give a better answer than myself.
