From 3 minutes and 34 seconds in the video linked, Pin talks about his ebony Blackmachine B2. Pin first became aware of Blackmachine guitars when Doug Campbell (founder, only luthier and only employee of Blackmachine) turned up backstage at a Sikth show with a selection of his guitars and requested that Pin try them out. He did, and "pretty much [hasn't] looked back since then".
He took the tone knob off of the guitar "because I didn't really have much need for it at the time".
He also mentioned he has another B2, which differs from the one in the video in that it has a mahogany and sapele body and a snakewood fingerboard, "they're tonally quite different, which keeps it interesting, gives me options when I'm choosing between them".
