The bottom row of holes features the same notes as the top row, tuned slightly higher. This special tuning creates the tremolos distinct sound, a beautiful vibrato effect with a richer tone. These harmonicas are primarily used in ballads, folk, reggae & gospel music. 24 double holes (48 Reeds). Brass Reedplates, and a Maple Comb. Available in the key of C.
