I'm considering installing Alembic p-ups and elecs in my Aria - I reckon their size is similar to original Aria p-ups... There's a big chance I'll be in the USA this autumn, I'll try to hunt something down!

You'll need a router for that, Alembic pickups (AXY) are bigger than the pickup in my Aria SB..

+/- 100x40mm for the Aria pickup and +/- 105x45mm for the Alembic pickup.
