Gallein Krueger MB500 amp head. The amp is in great shape. Also included are a set of rack wings and the rubber feet that came with this head. So you can mount the head if you wish in a studio or music rack. These amps were light and had phenomenal sound for bass, electric/acoustic guitar and even pedal steel guitar. I use mine in my pedal steel rig along side with a peavey duel deltafex . And have a lot of complements on the sound and tone of the amp without sacrificing power. listed down below are the amps specs.
NOTE Just the amp head,power chord, and wings are included in this listing. The other components, and rack unit are not for sale.
