I finally got around to testing the GHS Balanced Nickels. I got the 44-106 sets, both long scale and short scale.
I wasn't sure what to expect because I'm a huge fan of pure nickel roundwounds but generally not a big fan of GHS strings. I love how GHS roundwounds feel under the fingers, always very nice and smooth, but I've always preferred the SOUND and lifespan of other strings. For reference: I'm generally a big fan of Thomastik and Pyramid strings + some but definitely not all Roto sets.
I really like these GHS Balanced Nickels though. I still slightly prefer the sound of broken in Pyramid Pure Nickels but it's a close call. Both sound great for a smooth, fat roundwound tone. The Pyramids have a very unique smooth fatness when broken in and the GHS BNs aren't QUITE there but both sound GREAT.
Where they differ a lot is perceived tension. I say "perceived" because I have no idea about the actual tension figures. I guess "stiffness" would be a better term. The GHS BNs are more flexible, the Pyramid PNs are stiffer. Both are within what I would call "normal" stiffness though, not flabby or bridge cables. Having said that, I've only ever used the 45-105 Pyramids so I guess the lighter sets will be more flexible. But when comparing 45-105 Pyramid and 44-106 GHS the Pyramids definitely have a "tighter" feel. Which one is "best" will be purely down to personal taste but like I said, both are well within what I would call "normal" stiffness and I doubt anyone will dislike the tension/stiffness of either (and there's always lighter gauges available from both brands).
One huge advantage with the GHS BNs is that they don't have the long break in period of the Pyramids. The Pyramids sound very clanky (and not in a good way) before they reach their super smooth/fat broken in sound. This may take weeks or longer. When they do they are still my favourite but the GHS BNs are a very close second for a fat, smooth roundwound tone.
If I had to say ONE negative thing about the GHS BNs it would be that they seem to have worse than average tuning stability when brand new. Not a bit deal though, they've been very stable for me once they settled in.
I've only used the Balanced Nickels for about two weeks now so it remains to be seen how they will hold up in the long run. The Pyramids just get better and better with age and never seem to "die". They are a bit like flats in that regard. The Balanced Nickels seem to have a bit more traditional roundwound "feel" to them so I suspect they may not have this long term quality but like I said, this remains to be seen.
Definitely my favourite GHS strings, by far!
