Badass full range guitar amp that can connect to Bluetooth. Amp connects to App that has a library of pretty much any sound ever made. Obviously, you can create your own as well. Go from Death Metal to Banjo or have it change the tuning without touching your strings. Has a feature where you can play along with your favorite songs. Can also use it as a Bluetooth Speaker. Very impressive rig. In perfect condition.
