Long time for the 2nd post but here goes.
I sanded the body down to a smooth finish (up to around 800 grit). I was aware that some of the grain seemed to be slightly deeper than I expected. I had checked the item description and it said Basswood body. Having read up on Basswood, general consensus was that it didn't need grain filling as it was closed grain. It became very apparent after the first white layer that the grain stood out an awful lot BUT, I actually quite liked that look so I ploughed on regardless.
I have since looked at the item on the website again and there is conflicting information. In the item description it says the body is Ash and in the full item details it says the body is Basswood. So who knows!!!
Anyway, the body has had it's sanding sealer, white layer, red layer and now I'm onto black.

This is after the final layer of Red.

This is after the first layer of black.
Once I have finished the black layer I will leave it to dry for a while before commencing sanding / scraping to get to the final relic'd / worn design.
QUESTION!!!!!
I am looking at replacing the bridge single-coil with a hot rail I have from a previous guitar. Should I...
a) run direct to output jack and lose the volume / tone controls for this pickup
b) run through the pots as they are (250K) and lose some top-end for the hot rail
c) Other option?
