Success
Just put a set of Schallers on my new SE Angelus.
The upper bout screw I could reuse as the head was small, and it countersunk into the Schaller part.
There was also a black felt pad on the stock end pin which I reused.
Now down by the input jack there was no felt pad under the stock end pin, they forgot to install it?
No reason why there should not be one.
However...the stock screws head was bigger than the upper bouts one, so the screw head sat on top just a tad which caused the Schaller part mounted to the strap to not work.
I knew the drill, I would have to use one of the Schaller black screws.
They provide you with two, one long and fat, the other shorter and thin just like the stock SE screw.
I had extra felt pads (and Schaller now provides them where a year or more ago they did not) so I slipped one on the screw and Schaller end pin and screwed in the screw.
The threads are pretty much identical to the stock SE screw so all went well.
I also highly recommend one of these Stew Mac kits, I have used it before on the end pins and also the truss rod covers.
I have posted this kit before in other threads.
Very compact, and all your tools are in one nice little case that can fit into your hard case or gig bag.
