Hey Adam, I've just put through a test order. Maybe have an option for wrap-around bridge as previously mentioned by Simon. Dropdown for pickups would be nice but not sure how many combinations you would need. The checkout seems to work okay no issue

9mm for tuners option, is this for vintage sized machine heads? They usually require 8.75mm holes. I think 8mm maybe more suitable as an option then the buyer can enlarge if required with a reamer
