This tool helps you to practice and understand your equalization techniques.  With purchase you not only receive the tool, but also a 2 hour session with me - either in person, or online for those who are doing it from a distance - and I will go through EQ inside out.  By the end you will not only fully understand how EQ works, but also get some troubleshooting with me to find what part of your technique needs work.  
I have had a lot of success with past clients in working on EQ using this tool and my knowledge of what's going on inside.  If you are wanting to fix something, or simply just aim to understand it better, this is for you.
