FEEL THE RUMBLE. A high quality music player for the iPhone that gives the user full control of the bass. Take advantage of good headphones.
Directions:
Use the Gain (G) to adjust the volume level of specific frequencies (F). Set the gain high and low frequency until you get that clean bass you want.
Suitable for those who just want to enhance their listening experience with a little more kick to those who want their bass to reach "booty-shaking" proportions.
This app is meant to be used with headphones and attached speakers only.
