You just need to learn how to dial in your 6505. Those Crate Flexwaves are crap.

Although I also am not a fan of the sounds that the 6505 puts out, I will say that it would be a shitload better than that Crate combo. Like the guy above me said, learn how to dial it in correctly. Most important step in doing so: TURN THE GAIN DOWN! WAY DOWN!
