Terre Thunder WahWah S

​The Terre Thunder WahWah S is a simple, interesting percussion instrument designed to create a "thunder" rumble sound when shaken, and a "wah-wah" effect when striking the open end.
​On the positive side, for the price, this instrument is not bad. It's generally quite affordable, and for a bit of fun or an unusual sound effect, it can be a decent purchase. Some users report a very good sound quality relative to the cost.
​However, there is a significant and recurring quality control issue regarding the skin (drumhead). Unfortunately, the goatskin part frequently arrives or becomes bended or wrinkled. This often leads to a dull, unsatisfactory, or "cardboard-like" sound, rather than the intended thunderous rumble.
​It is true that the skin can sometimes be temporarily tightened or "repaired" with a hair dryer, which can improve the sound for a short period. But this fix is often fleeting, and the skin quickly returns to its wrinkled state. Constantly needing to heat the skin to maintain tone is impractical for regular use and is likely not worth the ongoing effort for such an inexpensive instrument.
​Overall, due to the inconsistent sound quality caused by the skin issues, the Terre Thunder WahWah is perhaps best recommended for children or for use in casual, non-critical settings like educational workshops, where sound quality is less paramount than the novelty of the effect. For serious musicians, the quality control issues are likely to be too frustrating.
