Bump. Has anybody tried both these and ghs pressurewounds and could maybe describe their differences?
I use both these strings extensively.
Playability:
I find both to be highly playable strings. The GHS are softer and nickel-plated (round core, I believe) and real easy to play on. The Labellas have more tension, but their tension in relation to other strings I've used is one of the things I really like about them.
Tone:
Labellas have a prounounced (but musical) midrange, combined with a strong (flatwound-like) fundmental.
GHS have that warm midrange tone that you get with nickel-plated strings, but with more fundamental (once they break in) than other nickel roundwounds I've used. That fundamental is one of the main reasons I use them.
The Labellas are closer to flats than the GHS Pwounds. They are to me, something like a flatwound string that is easier to play on. Having said that, however, there are flatwounds and there are "not flatwounds", and these are not flatwounds. They are stainless steel strings that have been ground down a bit and some of that tonal edginess & brightness you find in a steel roundwound is ground down with it.
String Life:
Both have a long string life, in the sense that as they get older, rather than just "go dead", they take on a different tonal characteristic, and for both it is the same: they both get more thuddy, warm & flatwound like. Pressurewounds are a great string if you are into playing on real dead roundwounds to emulate the sound (but not the string feel) of flatwounds.
The reason I use both these strings is because I have always searched for a string that lies in between flatwound & roundwound strings ("the best of both worlds"), and these two come the closest for me.
But I should say, maybe as a kind of disclaimer: I LOVE flatwound strings. Once you get used to the girth and the REAL (not eq'ed) fundamental + juicy midrange, it's real hard for me to use anything else. I want my bottom end to come from the bass & the strings, not from EQ.
Sadowsky flats are my string - very playable, with a very organic, woody sound.
