I can see where you might think it sounds dark and mid rangey without a lot of treble sparkle. This could be because you just got it and will grow into it as you bond with it and learn about the amp, where it's hot spots are and how to draw it out to your satisfaction. Also, it could be that it needs to be cranked up more to bloom, rather than be held back by a turned down volume or gain knob. It sounds like it would be really good for power chords without any further following of the learning curve and the Agile definitely sounds great. I also like your rythym.

With some time you might get this amp to sound way better. I hope my new Peavey 6505+ sounds as good when it comes in tomorrow. I need to learn how to post clips.
