Pickups are Entwistle AS57s, I'll see how they go.
The big switch is a Freeway Ultra. Positions 1, 2 and 3 are neck, both, bridge. Positions 4, 5 and 6 are series in-phase, series out-of-phase and parallel out-of-phase. The little toggle switch is a simple bright switch.
My understanding from the folks at Freeway is that master vol works in all switch positions as does master tone. Bridge volume works in position 3, or adjusts the mix of the bridge pickup in pos 2, 4, 5 and 6. That's the theory but I guess we'll see when I get it hooked up!!
I've just put everything on the proper pickguard and have tried to lay it in place but I'm going to have to expand the Freeway switch cavity - there's just too much wire to fit in the original space I had made! I don't have a lot of room to play with but hopefully I'll find a way. Might leave that to tomorrow morning with a clear head!
