1968 Ampeg B-15N
Some call this the "Holy Grail" of vintage tube bass amps.
It is hard to beat the classic tones that this amp can conjure. It doesn't hurt being in the revolutionary mobile configuration so you can take the party anywhere. This has acquired some wear over the past several decades. The grill is discolored, someone replaced all the original knobs with newer ones at some point and it has ripped vinyl in a few areas, but everything performs to perfection.
