MoonBassAlpha Posted April 9, 2012 Share Posted April 9, 2012 Hi all I just fixed up an old (mid 70s?) Marshall Bass 30 amp for a friend, 2x12 speakers arranged vertically. They are 25 W Celestion Greenbacks with 75 c/s resonance freq. Does anyone know when they changed over to putting Hz on the labels? Might help date the speakers, as I suspect they're worth a lot more parted out (to guitarists!) than the amp is all together, as it is a bit big for a practice amp and a bit quiet to be useful! Any insight gratefully received, I haven't even been able to find a picture on t'internet, hey it might even be really rare! (still doesn't make it any good though!) Cheers Jules Quote Link to comment Share on other sites More sharing options...
skankdelvar Posted April 9, 2012 Share Posted April 9, 2012 4 page 'Dating a Celestion Greenback thread here: [url="http://www.thegearpage.net/board/archive/index.php/t-67646.html"]http://www.thegearpage.net/board/archive/index.php/t-67646.html[/url] Dunno if the info you need is in there because I started reading it and my brain dried out. Good luck in your quest Quote Link to comment Share on other sites More sharing options...
Big_Stu Posted April 9, 2012 Share Posted April 9, 2012 My son's band were sold two old Marshall 4 x 12" PA columns for £60 that they soon didn't want because they looked too old & weren't loud enough. They each had Celestion "pre-Rola*" Greenbacks in (which I was assured were the ones that are sought after) and paid for quite a bit of gear for them. * No, I don't know either.

MoonBassAlpha Posted April 9, 2012 Author Share Posted April 9, 2012 Thanks Skanky, that may well help if I can be bothered to plough through it too. I wish I'd taken some photos and copped the date codes off the pots while it was in bits.... Hindsight 20-20 etc. Quote Link to comment Share on other sites More sharing options...
