I discovered a good relicing technique - let your teenage kids use your gear. Sooo many more dings in everything now. Even the walls.
Not so much of a fashion, but they are especially talented at relicing my f*****g leads! It’s like a bowl of rice crispies when I plug anything in.
On a more serious note, that Monty’s stuff on the fretboard seems great (though your board seems nicely dark already in the pic). Also stick a lit fag behind the nut on the E string and let it scorch the wood!
