It's not a lightweight combo, no--but it has
plenty of power and the classic GK tone controls. It's a biamp rig, so there's a separate amp (with volume control) for the tweeter, independent of the main amp for the speakers.
GK discontinued this model, but here are the description and specs:

It's got a pullout luggage-style handle on top and casters on the bottom, so it rolls around pretty easily. As you can see from the pix, it's in excellent condition. No functional problems. A chunk of rubber came off one of the casters; it rolls fine so I never bothered to replace it. It's been a faithful companion for several years, and I'm only selling it because I got into mixing and matching separate heads and cabs.
You can have it for
$575, local pickup--which would be Huntington WV 25701. I'm willing to drive a little bit to meet up. PayPal is fine.
I'll ship it in the original GK box if you pay for shipping. I recently had an unpleasant surprise about UPS rates for shipping a cab, so if you want me to ship it to you, send me your ZIP code so we'll both know what the ticket is.
