German stringmaker Pyramid has made some special strings, suitable for “electric” (working with electro-magnetic pickup) full size sitars. They make brass wound polished strings for laraj & kharaj 0.55mm (.021) & 0.74mm (.030) and heavy kharaj 0.92mm (.036). And also brass coated steel wire ranging from 0.18mm (.007) to 0.38mm (.015), good for all other strings such as tarav, cikari, baj and jora tar.
I ‘ve ordered and tried the brass flatwounds for laraj & kharaj and brass coated steel wire for jora on my SAS-01 and SAS-02. The brass flatwounds sound very good, brilliant and accurate but a little more harsh than I am used with the bronze flatwounds from India. They are also not as flat as their bronze indian brothers. But the latter are very fragile. The bronze winding breaks easily while playing heavy meend. I don’t know (yet) how strong the pyramids are. The brass coated steel wire behaves quite similar to the full steel jora string. There is a noticeable improvement to the jora tar tuning problem but the overall sound volume remains the same. I had hoped that by using this brass coating the volume difference between baj and jora tar would become less. There is only a very small improvement. The only solution seems to be the fitting of a thinner jora string. Or, maybe someone can make me some bronze coated steel wire instead of brass coated ??
