[Removing The UST ?]

Removed the UST on two J45's and very happy I did.  I also dropped in bone saddles.  The biggest difference I noticed was more volume.  I think the tone was more clear but not a significant difference there.  As others have said,. It just feels right now.

[Rediscovering Gibson Masterbuilt Strings...]

I too like the Gibson strings on my J45's. I have used D'Addario for years on my other Gibsons but they just don't sound right to me on the J45's.  Interesting tho is I like the PB's on the rosewood custom and 80/20's on the other.
