How ya livin'? I'm interested in any feedback on this amps ability to be heard in small gigs and rehearsal. I won't be competing against Marshall stacks,however, getting lost in the mix isn't all that cool either. I'm trying to drop the "bigger is better" notion and find a quality rig that is portable,capable of producing great tone, and loud enough to handle my gigging situations. Would you experienced users recommend an extension speaker? Makes sense to me for "stereo" effect. Or,should I scrap this and go with the WM 15 for it's greater power? Thank you.
