well, i have a rogue amp right now (pretty sure its a 15). i want to upgrade soon, but im not sure where to start. i know that i want something that will last a while. i also dont care for the one's w/ the tube sound ( sounds like the sound is circling its way inside a bottle or something). i want something w/ BASS! but i have no idea what.....im dumb right now when it comes to amps, i know where to plug things into, and how to adjust the sound. and that is about it......help!
