I've had two, a German V '63 (sold years ago) and my HCT 500/1 and man, it is impossible to truly intonate these guys. Floating bridge, fixed saddles made of fret wire so of course you just get the E and G as best you can. The luthier I go to, a German chap no less, kinda, maybe likes them but mostly hates them. His bass player has a vintage model from the 60s and of course my friend does the work on it and as I recall, tuning stability is a pain. My Contemporary is not quite four years old and.. mostly ok. It's got a really weird/wicked warble going from a A to a G (D string 7th to 5th fret or A 12th to 10th) any season other than summer which forces me to play the G staccato whether I want to or not. The stock strings were rounds, .040 - .095. After a couple months or so I put La Bella flats on it, .039 - .096, or rather he did since I was changing type and gauge and hadn't started doing basic setups yet and that when it got more weird. With the rounds, the bridge was angled the normal way - furthest from the pickup on the bass side, closest on the treble side. I remember when I went to pick it up he said "Don't let anyone tell you this is wrong. It's the only way it will intonate!" and it was reversed, dramatically closer on the bass side. Well, I just changed the strings and thought I'd experiment myself since I've never played with it beyond bridge height so I moved it back to the normal positioning and ouch. Forget about it! So I put it back to the weird way and got it as close as possible. Still a little flat but I can't move it any closer on the G side because of that stupid pin from the pick guard to the the bridge. I actually had the G perfect until I realised I'd bowed the pick guard a little. Between that and the periodic buzz no wonder McCartney took his off completely. My favourite thing about the Contemporary series... it came with a tiny white Made in China sticker. Hofner won't put it on the headstock! They put "Designed in Germany". Hahaha German engineering and pride.
