As a traditional instrument manufacturer in the midst of Kolkata, Monoj Kumar Sardar supplies an extraordinarily high-quality Surbahar.The Surbahar which is usually tuned a fourth lower than the Sitar, could be called a bass Sitar. Consequently, the Surbahar is significantly longer than a Sitar and also has a wider neck. The full, low sound is especially effective in the quiet, meditative Alap. Also in Dhrupad style its sound pattern is unmatched. Contrary to Sitars, Surbahars are less standardised and are thus available on the market in lots of different sizes and shapes and with different features and decorations. This supports, together with the particular sound pattern, the special individual aura that is attached to this instrument and thus makes it an instrument for individualists and for enthusiasts of special instruments.

Monoj Kumar Sardar supplies a reliably good quality, both in processing and in sound characteristics, and can in every respect be called a manufacturer of excellent instruments with a good price-performance ratio.
