First time I have tried covering the left end using masking tape to reduce the volume of bass. most of the holes except 2 square mm so that the wind can be released.
I am happy with the result and the constant supply of bass drone doesn't overpower the melody.
Played on Hayden Duet Concertina (Troubadour)
