I ordered this amp last week after viewing some YouTube vids. This amp is a game-changer for S>S> amps. I"m a dedicated "tube snob", and I've put all my Boogies, Fenders and Marshall's in the closet. I just can't stop playing it. I can pick it up with 2 fingers and gig all night long - no need for stomp boxes, multi-FX, etc. How can a sound so huge ("yuge") come from this light, inexpensive amp!!!! I LOVE IT. BTW - I've been playing for over 50 years.
