The mouthpiece on my Yemenite Shofar is too small; can it be widened?
The Shofar Man has people send him Shofars all the time from all over the world to modify or widen the Shofar mouthpieces for them. Many people that could not get a sound out of their Shofars can play them wonderfully after the Shofa has been widened. The Shofar Man has also shown many people how to modify the mouthpiece of their own shofar.
