All of the Grabbers he used back in the day had one piece maple necks.
Mmmmm... they all have scarf joints, so are they
really one piece??
Gene's wine red grabber was one of those (I think) earlier ones with the weird "negative pitch" headstock. The black one (which, IIRC, was passed on to Mark "The Animal" Mendoza) had a conventionally pitched 'stock.
