I recently decided to make my old 4-string my dedicated 'heavy' bass. I was gunna put some heavy gauge strings on it and change out the pickups cause I'm not a fan of the sound my old ones have anymore. I was just wondering what's the process you do for putting in new pickups? I understand there's wiring that needs to be done and such but also do i have to take measurements so that I know the new pickups will fit nicely into my bass? It's an Ibanez BTB btw
Thanks
