(You can reload the Bass Enhancer AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Bass Enhancer AUv3 plug-in comes as In-App Purchase. Does your bass sound dull and lifeless? Red Rock Sound Bass Enhancer will be your choice to correct this deficiency.
