Loaded Synthetic Lute Bass and Meanes Strings CD type

It can be mounted on these instruments



…there is another sort of strings, which they call Pistoy basses, which I conceive are none other than thick Venice-Catlins, which are commonly dyed, with a deep dark red colour.”

(Thomas Mace “Musick’s Monument” London 1676)


Warning! Please use the string only as basses not octaves. Maximum tension should not exceed 4,5 kg!


The appearing of wound strings caused, starting from the end of the 17th century, the definitive abandoning of the ancient manufacturing techniques of the traditional all-gut bass strings.

This explains why modern plain gut strings fail to produce an acceptable acoustical performance in the low registers, thus making it unavoidable to use wound strings for musical repertoires that actually pre-date their historical appearing; this, in turn, causes an obvious philological paradox as well as serious tone and balance problems between high and low registers, especially on Lutes.

We think that the old all gut Lute basses had an higher density to achieve better performances.

Here are some points:

  1. A large number of bass stringhole diameters recorded from original Lute bridges dating from the late 16th and 17th century shows that those holes are too small to allow plain gut strings a sufficient working tension at the proper pitch. An unloaded gut string able to cross these holes should have a tension ranging form .9 till 1.2 Kg only. This mean to drop a moderrn lute of 9 till 11 semitone that need to achivie  such range of tensions.

2. Musical iconography from the 17th century and a bit latter  often  shows  the Lute bass strings of quite different colors from that of plain gut, varying from dark red to brown. They are also positioned  were  today we find the wound strings, i.e. from the 6th course down in the bottom.

3. Some treatises of the XVII Century  wrotes that the Lute  strings had a remarkable sustain and acoustical power, ables to cover the sound of the upper strings (see Mersenne ‘Harmonie Universelle’, Paris 1636; ‘The Mary  Burwell Lute Tutor’, 1670 ca; Thomas Mace: ‘Musick’s Monument’ London  1676).

4. On several paintings of the 17 th C. , most of the Lute bass strings has a relative small gauges if comparated with the gauge that an  unload natural gut strings should be have.

All these considerations suggests the idea that gut bass strings were made densier: the loading of gut, a technological strategy that we believe employed by the old stringmakers in order to have the Lute bass strings  much more performant.



The CD bass Lute & Baroque guitar strings are smooth synthetic loaded strings  characterized by a high, standardized specific weight, achieved by a loading extruding process with very  thin metallic copper powder made in the range of 115 CD till 220 CD.

Diameters smaller than 115 CD are manufactured with an half loading degree, in order to be useful for the  4 & 5th Lute courses (called  in the past ‘Meanes’) .

We  do not use Mercury or Lead compounds; we use thin metallic copper powder (that is not toxic)

Surface: raf; same of rectified gut

Strong, warm  and percussive tone, without the excessive brightness typical of modern wound strings, perfectly coherent with the tone and dynamics character of gut strings as well a synthetic strings. Excellent tuning stability; far better than any plain gut, synthetics and wound strings available today.



To keep calculations simple and make it possible to use any available string-calculator, CD  synthetic loaded  strings, as well as wound Nylgut ones and the D type, are referred to by a letter following a number indicating the theoretical equivalent diameter of a solid plain gut string.
E. g. “140 CD” stands for a loaded string (indicated by the letter “CD” ) corresponding to a high twist gut of 1.40 mm. in diameter.

The actual diameter of the strings is, of course, smaller but under playing conditions it will have the same working tension as a gut string of 1.40 mm. diameter at equal pitch and same string length.
