amewse Posted February 6, 2013 Share Posted February 6, 2013 I have a Kramer 450B with a damaged Schaller M4 Machine head on the treble side. The string post has broken at the base of the slot. I have been looking for a replacement but this type are a bit scarce. Schaller say they can be dismantled but only by destroying the inscribed cover on the back. I just wondered whether anyone has managed to get one apart without destroying the cover, it is a push fit apparently. Any help would be greatly appreciated. If any one has a spare one I would be interested in buying or swapping for the full set of later M4's seen below. Angus. This is what I need [IMG]http://i1353.photobucket.com/albums/q668/amewse/image_zpsd5b67377.jpg[/IMG] These are available for a swap.

The Bass Doc Posted February 6, 2013 Share Posted February 6, 2013 I did dismantle one of these years ago. As far as I recall it involved drilling a small hole in the perimeter of the cover into which a 'progger' could be inserted to help prise it off. Good luck if you're going to try this Quote Link to comment Share on other sites More sharing options...
The Bass Doc Posted February 6, 2013 Share Posted February 6, 2013 I assume you will try to fit the post from one of the other M4 types. If so, I will be interested in acquiring the remainder as I often get asked for spares Quote Link to comment Share on other sites More sharing options...
amewse Posted February 6, 2013 Author Share Posted February 6, 2013 (edited) Thanks for the advice, seems like a good plan, I think a bit of heat may help too. I bought the later set to supply a new string post but it seems a shame to butcher one if I can avoid it. I still hope to find a replacement but am offering the full set as swap, someone may have one lurking in a drawer somewhere! I will let you know I get on.

BassBod Posted February 7, 2013 Share Posted February 7, 2013 I sold a 5 string set of these to Shaggy a few years ago - he had the same issue with an old Kramer. Might be worth a PM to see if he's got any left over? Quote Link to comment Share on other sites More sharing options...
amewse Posted February 7, 2013 Author Share Posted February 7, 2013 Thanks BassBod, I will drop him a message. Quote Link to comment Share on other sites More sharing options...
