I originally bought a number of sets for a Larrivee Hog top that I also thought lacked pop and snap. These strings, some Markley 80-20s and other sets designated as "BRIGHT" did not do what I wanted to for that guitar either.
The feel and playability of these strings seem okay, and I am convinced that they would work well on a dreadnaught or some other guitar that simply needs more focus. If you want BRIGHT as in TREBLE, I am not sure if these are the set. I dig a lot of the other DR sets for my various guitars though (Sunbeams are some of the best strings out there in my experience, and the RARE strings are great for adding depth to cheaper guitars), and have deep respect for the company.
Put them on... record. Wait a few days... listen again closely.
Previous strings: D'Addario Phosphor Bonse. (I tried Martins... didn't like them.) The guitar: Garrison G-10 (the Canadian built version - not the Chinese one.)
80/20 Hi-Beams are brighter. Not a whole lot, but it shows up in recording and it shows up in the harmonics I hear. It isn't a "night and day" difference but pleasing. It loses some of that thumping range though.
I checked intonation. Previously intonation was out somewhat on all the strings (age, slight lifting of the top) As it was out by 20 cents or so on all strings and I don't really play in a band against other instruments that would measue it this wasn't an issue.
The intonation of the HiBeams is good for most strings but out for the E & A. I'm thinking "top heavy" strings to correct this on a next try (higher tension - same tuning.)
To be fair I haven't tried it against the D'Addario 80/20's. If the intonation balanced perfectly I'd give these 5 stars and not try another. As it is I'll carry on the search over time. I'm patient.
Nothing wrong with the strings... nice, bright enough, certainly nice harmonics.
