I have a Rick 330 copy kit, it was ok, took ages to get set up decently ready to build though as none of the parts quite lined up properly, so loads of measuring and faffing and dremeling to get everything lining up just right.
I know somebody else who has had a couple, hardware quality especially the machine heads is usually pretty poor, the only hardware that did get replaced straight away was the heads though,the rest when he had the time and the money. Getting the headstock right can be a pain if it’s not pre cut,be prepared to spend a long time trimming and getting a good fit on parts.be prepared to spend ages getting the finish decent.
I wouldn’t bother again. but I’m glad I did if you see what I mean.
