That's a nice Custom.
Looks like one of the resin infused tops, but using a burled maple rather than buckeye, maybe? The matched headstock is bonus points, especially for Fender-folk.
If I was guessing, I'd agree probably Vol./Pan/Filt. but could also be old-school Persuader, 2 Volume and Filter. Just thinking, the person who orders a JB shaped Custom Alembic may prefer 2 Volume pots...
