Schlagwerk Wah-Wah Tubes Set of 5 F-Penta

The aluminium tubular bells produce a long-lasting sound, rich in overtones. A fascinating wah-wah effect can be created by opening and closing the small resonant hole. The three single tubes 120, 270, 320 are NOT harmonic instruments they are more ?resonating? tubes and are not tuned to a certain pitch.
