Suzuki 2 Timer SU21 and SU24 21 Hole and 24 Hole For the sound of yesterday from the technology of today, the Suzuki 2 Timer harmonica is sure to bring back memories. The 2 Timer has a traditional sound quality made possible by a dual hole octave/tremolo tuning action, excellent for folk and country style playing. The Suzuki harmonica's laser tuned reeds are extra lightweight to give that special harmonica octave effect. The 2 Time Tremolo is available in 21 and 24 note models. It comes in a soft lined hard shell case.
