Meinl KA9WW-BK Wah-Wah KalimbaEverybody loves a little wha wha, so we came up with a kalimba with a body oriented sound hole in place of the traditional style. You can create a great wha wha effect by simply bouncing the kalimba body on and off your stomach as you play. The position is comfortable and natural, while the sound gets shifted in creative ways.
