I'm getting back into this after a long absence. Any body have any experience with the JHS little black amp box? I just don't understand how it would really work. I'm picking up a Bugera 6262 2x12 (I've heard good things and horror stories but $229) combo in a day or two It's 120 watts so I know it will be very loud. I can't afford an attenuator just yet and ran across these things. Any help here?
