These have become the standard purchase for my sitar. You get the high quality of the pyramid strings without the extra cost of buying the sympathetic strings everytime you need a new baaj (melody string).
I found the tonal quality of these strings to be great - I only wish that I could get a slightly thicker baaj - as I prefer heavier gauges. I can't find any other place for silver-plated steel, so I make do with what there is. However, it is likely that you will consider this a blessing, especially for people new to sitar - as the ease of playing is increased with these strings. (note: I can only say this is true for my sitar, but I get the feeling others have the same experience)
I switched to pyramid strings when I got my new sitar. I had trouble with the nickel/silver frets getting scratched by plain steel strings. For anyone else with this problem, the silver-plating does make all the difference, and I'm very glad I gave these strings a try. And so is my sitar!
These are excellent strings, they sound really good and are a pleasure to play. The first string seems to be lower tension than the one I used previously and is easy on the fingers when bending it. My only criticism is that it is quite hard to twist the metal to make loop ends for the 5th to 7th strings. Would it be too much to ask that these strings could come with ready-made loop ends?
Also, it would be useful if the description on the website could make it clear these are for Ravi Shankar style tuning, i.e. Ma, Sa, Pa, Sa, Pa, Sa, Sa, not for standard tuning.
