I bought a kawala, to learn it from here. I would say it wasn't in best condition/quality , as the copper was removed while unwrapping it.#
It also came with multiple deep cracks on it, these cracks are not just on the surface, there like a long holes on the first knuckle. is that okay for a kawala?!
I watched a kawala tutorial but it won't make any sound, and that instructor said that the first knuckle is important for making the sound, does these cracks related to that issue
