I have played several recent MIM basses and have had no complaints - the QC of some of the earlier ones may have been inconsistent however look at the roadworn and vintage series - I reckon the early roadworns will become the JVs of the next decade.
I agree that the Pawnshop VI and the MIJ VIs are of different price points and there may be some compromises in terms of materials used however they are a similar animal and we all know how 'off the peg' Fenders differ in quality and appeal. We've all heard stories about 'those Japanese Squiers' that blow some USA Fenders out of the water.....no this is not an urban myth I own one that cost a sixth of what I paid for my '74 P. Bass and equals it in terms of quality
I'd like to compare the necks - for example I've heard the Pawnshop has a flatter profile with a slightly wider string spacing and jumbo frets, I believe this is to appeal more to established bassists since the Bass VI has been regarded as a 'guitarist's bass/bassist's guitar' by its critics.
My Bass VI is a beautiful instrument and top spec, one piece body, quality construction and materials yet the setup and stock strings were awful. I like the pickup configuration and switching options - very different with the Pawnshop version. I'm really looking forward to playing one!
