Good calls on the Gotoh, dave - the whale tale is shallower and further back and doesnt interfere with picking at all, and the posts were wider - a pain when you dont have a drill bit of the correct diameter!
Got it all in though. This things very nice. Well put together bit of kit. No idea how it stands up to abuse though - I quite likely wont. Its locked down at the moment. maybe if the whim takes me.
