Description
17-Inch Professional Three-Reed Shruti Box, 440 Hz
Create a broad, layered acoustic drone with the RagaLoom 17-inch Professional Three-Reed Shruti Box. Built in teak wood and tuned to A=440 Hz, this expanded model provides 36 selectable notes from C to B across three octaves—far more tonal flexibility than a standard single-row shruti box.
Three octaves for a deeper, more flexible drone
