Query: Avoid at all costs.

After my Sony CPA9C broke, I decided to get a new cassette adapter.Immediately, I notice that everything is written to the middle eq channel in my car. There was no treble to speak of, and as an emulated bass, there was an audible flapping sound whenever there was a beat of any kind.I would seriously avoid this product at all costs.Also, we need the option for a zero-star.
