Hahahaha, the fretboard is NOT dirty, man. It's just worn out.
It is a maple (?) fretboard and it was stained in black, so it used to look like ebony.
After years of playing and concentrated alcohol cleaning, the fretboard faded to its natural colour and only sporadic dark spots remained, leaving the impression that it was dirty.
The body was messed up with both paint and stickers. Everything you see on this pic is gone - it is bare wood now and its shape is completely different.
The body looks so elegant now and it's not that beefy anymore.
By the way, my main dilemma about the finish is: Paint & laquer or just bare wood & laquer?
Paint would make it look like plastic, while bare wood would make it look more alive and rock & roll.
On the other hand, paint gives me the ability to use putty which in turn would help me make the top of the body harder.
What do you think? Which one should I use?
