Hi looking to start my Rcm-1 which will be my third Pitbull guitar the first 2 being the sta-1 and the tl-1 .

In regards to the body im going to grain fill, then sanding sealer the back before a solid colour, with the veneer top do i just sand it and paint or do i have to fill/seal this aswell? (whole guitar will be soid color)

With the neck and headstock being mahogany, do i fill/seal this aswell? (previous guitars i just sanded/stained but they were closed grain)

Also with the pickups they are advertised as humbuckers......does anyone know what they look like with the cover off?
Just like coverless humbuckers but smaller?

Thanks Mark
