This is a simple to use and hear equalizer and amp. The presets make it easy to try different setups to find what sounds right to you. You can also set up your own custom EQ and save it. The amp lets you add some volume if you need it (I did). One word of advice, make sure you hit the refresh button to ensure your current selection is being used and ON. Thank you to the developer for an easy to use AMP/EQ. Well done.
