I was just wondering if there are any tremolo harmonica players out there. The tremolo is a lovely instrument to play along with a dulcimer. Basic good quality tremolos can be bought for as little as $20.00 to your door in all keys. Keys of D & A sound the best with dulcimers. Just my two cents.
If you're interested, there is a new web site dedicated to the tremolo:
