These strings are on an early eighties Musician, 34 inch thin neck-thru, swamp ash body with PJ Barts.
Word of caution: The outer wrap went part way around the tuner post on the E and G strings. Fit may be a problem on some 34 inch guitars.
These are a very low tension string and with the thin neck, I was unable to relieve the tension rod enough to set up the action to my liking. With that said, and even with the slightly elevated strings, the action was very fast due to the incredibly light touch and relatively slick feel.
After only a few hours of play-time the strings lost their initial brittleness and settled into sweet lead-crystal highs, slightly scooped mids (but still more than enough to produce some satisfying growls) and some of the richest fundamentals I've heard. All in all a very pleasing sound with great detail and lots of interesting harmonics. In my never-ending search for "that sound" these strings are currently in the number one position.
Bonus: These strings now have about 200 playing hours on them with little deterioration in sound quality or feel.
I will be buying these again (in a heavier gauge) and will be trying DR's Low Beams and Fat Beams as well. Very impressive!
