Thanks for the great information Neil and Skidlid. :thumbsup
I've sent an email to SPX Loewener about the tool so I hope I'll get info on price and availability soon.
I didn't know there were other tension tools available, but with Skidlids info and a search on the board shows there are quite a few:
- Snap-on ??
- Facom DM.16
- AST 4395
- Clavis (expensive? easy to check 98Hz though)
The AST is interesting, is that using the Loewener scale?
