Frequency Spectrum Guidelines

Need guidance? You might want to start reading the simple guidelines below.

All you really want to do is to be able to hear a frequency that you like or don't like and be able to identify which range it falls in in the table below. If you can do that, you're golden in terms of EQ speed and skill. -- Jared H.
