To be honest, I've just sold my 4003 after 8 years of ownership; in essence it's just me becoming less tolerant of the ergonomics as I get older and grouchier. I could live with the pup ironware (I put in one of the aftermarket thumb rests/gap cover), the overly clubby neck-headstock transition and the agricultural bridge. With time though I did find the body binding on the forearm an unnecessary inconvenience to me when playing standing.
All that said, I may look at a Rick again if the stupid price inflation situation stabilises BUT it would be a 4003S.
