These may well be great strings, but unless someone clearly demonstrates how to trim these so they will work with a FR, I won't spending another $18 on them.
Con: they cost a lot, and that's all.
Pros: these strings are the most responsive, dynamic, beautiful sounding strings I've ever played. I've been playing since I was 11, now I'm 58, so do the math. I've used everything out there, these strings are IT. I use the be bop set on my archtop jazz box, I use blues sliders on all my electrics (2 PRS, a Les Paul, a strat, 3 teles and a couple others, p-90s and humbuckers) and the plectrum model on my acoustic. Once you get used to these strings, you'll notice the difference when you 'switch back'. i used to use D'adarrios, GHS and Elixir. No more.
touch sensitive as Katrina Law. Durable and reliable. Outstanding Tone demands Blue Sliders. They are worth the extra cost. A Big A+++.
This was like a visit to the tech and a new pair of pick-ups. All of a sudden I had a real mid-range, better balance and greater tonal range.
Lots of color, easy to play without being rubber bands. These are a real joy.
I am pretty picky about sound, especially tonal clarity. I have found that not only does my clean signal sound better, but heavy gain sounds better as well across a range of amplifier models.
I encourage you to give them a try.
These are a tie with two others (Pyramid and Pirazzi), for my favorite strings. All of which, of course, have their own individual characteristics, but these have captured my attention of late. Be advised, this review is application specific to a CS 52 (ri) Tele/Supro 24.
