Ken Loa Go with Wooden Bell (Vietnamese Suona)

I inquired and bought 2 extra reeds, but all 4 reeds are flawed and do not buzz. I have experience...I own and played my father's Shriner Suona from the 60s and the reeds were not these, both cane reeds are too large, the plastic ones are split on the sides and do not buzz. So it's an ornament not an instrument. I'll look elsewhere for the real reeds.
