So I have this Jay Turser Strat Copy.
Something similar to that^

Do you guys think it'd be worthwhile to change out the pickups for this
And this
Would it turn out to be a worthwhile project guitar? Worth gigging with?
Depends. Changing the pickups would probably help if you have a decent amp and don't like the tone you're getting. The locking tuners would help if you're having tuning issues. So it basically depends on what you want out of the guitar and what you currently don't like about it
My Soundcloud
Always up for some C4C, been compared to Frank Turner, The Cure's Robert Smith and Bruce Springsteen so check out my stuff if you like the sound of that
