This speaker and cabinet are in good condition. This WAS a GK bass combo amp. The solid-state amp died and could not be repaired, which left me with a 1-12" bass cab. It sits flat or can kick back for easier listening on a noisy stage. If you have one of the portable bass heads, this cab will make a great main or extension cab.
Opening is 12 1/2" x 2 1/2" if you're wanting to add a head.
