Savarez 500AJ

I currently use only carbon fibre strings on my nylon string guitars, mainly for three reasons:

1. They stay in tune long like metal strings normally
2. The are not that sensible on environmental conditions like temperature and humidity
3. They have more bright sound, almost like flameco strings

Savarez has sets with half nylon half carbon fibre. I prefer all carbonfible for the above reasons.

No, don't worry, I'm not confusing this with my Ann Summers review...
Happy with these strings, the 1st carbon trebles I have used, after deciding to see what all the fuss is about. Have used these for over a month now on an OK but inexpensive laminated spruce top classical. Definitely a difference in the projection of the trebles, and as new, the strings settle into the required pitch much quicker than nylons.
Would be interested in the difference of a more expensive guitar.
As these are high tension I am using these for slightly lower tunings like D or EB standard, or DADGAD etc.
Seem to be pretty good value. I also bought the red and blue (high bass medium trebles) set from Savarez, which are yet to go on my other classical guitar.
Perhaps for me ultimately there will be a hybrid approach having a carbon G, accompanied by other types of trebles for that tonal interplay (hence my personal reason for rating 4stars on the sound aspect)
The look of their competitor's Pro-arte half sets, are more appealing for the innovator in me, for customising tensions and tunings, but are more costly.
I think you could do worse than these strings if you wish to explore the carbon trebles.

As a freelance guitar teacher, I play about 4 hours a day on my guitar.
Strings has to tolerate a lot.
I have experimented a lot with strings: different brands, tensions, ...
For more then 10 years, I absolutely us the SAVAREZ Alliance-Corum High tension strings for several reasons:
1. clear and brilliant sound
2. stays well tuned
3. nice touch and subtile in playability
4. long life
These strings are not cheap, but they are more than worth their price.
