Query: muddy pitches

I really tried to like this product. It's such a great price for "trying on" a new instrument. I'm savvy enough to expect some non-harmonic tones along with the fundamentals of steel drum notes, but this drum's pitches were realllly muddy. I even took it to my choir director to see if he could hear an accurate pitch, but he couldn't think of a way to use something with such vague tones. Sad, I returned the toy.
