Judging by the amount of warm, clear definition the 'Stormy Mondays' added to my Les Paul Standard, I can imagine them being just ideal for a 'semi' like yours. I also had the pre-buying jitters, but after I had fitted them - wished I had have bought them a long time ago...
The treble is just so sweet and rounded (but never dull) with these, and the note definition/detail = wow !
:D
