Savarez 540

- 540R / Normal Tension
- 540J / High Tension
- 540ARJ / Treb: Normal Tension / Basses: High Tension
- 540 RH / Normal tension

The 540R, 540J, 540ARJ sets are made up :

* KF ALLIANCE plain composite trebles (so called carbon strings),
* HT CLASSIC stabilon multifilament (specifically treated nylon) wound basses with rust protected silver plated metal.

The 540RH set is made up of :

* KF ALLIANCE monofilament plain composite trebles,
* HT CLASSIC polished wound basses offering a flat surface.

These strings are the result of extensive research and high technologies requiring high-tech raw materials.

These 4 sets are very well balanced KF ALLIANCE trebles make up other sets: ALLIANCE/CORUM sets (cf. the ALLIANCE/CORUM range)
1 - THE KF ALLIANCE TREBLES
Research:

These strings are made of the now well-known composite monofilament ALLIANCE KF (some people call them carbon strings) , exclusive to Savarez. Years of research have been necessary to adapt this material to the demands of the musicians and to get an outstanding product for music uses.

The use of KF ALLIANCE material first introduced by Savarez, changed the world of guitar. The strings were first made of gut then made of nylon. The trebles are now made of a high technological material, very different from nylon : different elasticity, higher density, further longevity thanks to the very specific cristallinity grade.

In fact we have been working on the following topics to guarantee the technological and acoustic qualities of this material to make it convenient for music strings :

* Tensile strength,
* Mastery of the elasticity and elongation,
* Control of the geometrical regularity of the diameter for a perfect intonation.

The gauge obtained is absolutely regular without resorting to a mechanical polishing. The string gauge control is done throughout the manufacturing process. The last laser control is done when packaging,
Solving the fraying phenomenon (defibrillation): typically bound to any composite material, due to the breaking of the links between molecules. This phenomenon leads to the appearance of small superficial threads (until the string breaks) under a given tension.
We do actually master these various parameters. Thus we have the sufficient knowledge to adapt the material to the use of harmonic strings for other instruments: violin, harp, lute, etc.
Characteristics - Technology:

The KF ALLIANCE fibre has the same density and elongation properties as gut.

Its density is higher than the polyamide fibres.

The KF ALLIANCE strings are thinner than the nylon ones. They can resist a 35kg tension (harp).

The low internal frictions between the molecules increase the durability of the string beside a sustained sound.

(Mi-E1, Si-B2, Sol-G3) monofilament. The G-3rd string provides a great homogeneous transition between the B-2nd and the D-4th. It ideally balances with the other strings of the set in terms of sound quality. It is no more necessary to use a G wound string to balance the set.
Acoustics properties:

- Bright tone and clean sound,
- Richness of sound,
- Very extensive possibilities,
- Incomparable power and projection of the sound,
- An even greater sustained sound,
- Very clear sound on the high and very high positions.

The KF ALLIANCE also make up the CORUM ALLIANCE sets in which they are coupled with CORUM basses (cf. the CORUM ALLIANCE range).
2 - THE ALLIANCE/HT CLASSIC SET WOUND BASSES

Silver-plated wound strings are made according to a more traditional design and elaborated technology to offer a fast response, a brighter and more brilliant sound. They are rust protected.

They are stiffer (giving the feeling of a stiff string, not to be confused with elasticity) and allow a powerful playing.

They offer more resistance under the right hand fingers while facilitating the left hand velocity.
Acoustics characteristics:

- Reach and brilliant tone,
- Great projection,
- Percussive sound,
- An accurate and quick response,
- Sound and power.

In the 540 RH set, they are wound and polished.
3 - THE POLISHED HT CLASSIC BASSES OF 540RH SET

Round silver wound polished ALLIANCE/HT CLASSIC basses.

The string remains flexible thanks to the round winding.

The polishing eliminates the left hand squeak and offers a smooth surface to the touch while keeping the former acoustic characteristics.

Thanks to a very special technology they keep the high level characteristics offered by the round wound strings. They still offer:

a brilliance similar to the round wound strings,
a rich, mellow and bright sound thanks to the metal used for winding.
"4 - TENSIONS

The ALLIANCE/HT CLASSIC set comes in :

normal or high tension (540R set normal tension and 540J set high tension),
mixed tension normal/high (540ARJ red/blue set), trebles coming in normal tension (red) basses coming in high tension (blue).

These HT CLASSIC basses high tension, blue colour, offer the behaviour of a stiffer strings set and give the sounding board a higher tension which facilitates its vibration, the ALLIANCE/HT CLASSIC set made up polished basses (540RH) only comes in normal tension.
