If you are looking for that pure, unadulterated 1970s solid-state muscle, this is it. We have a killer, gig-ready Acoustic Control Corporation stack featuring the Model 330 head sitting right on top of its partner-in-crime, the Model 403 4x12 speaker cabinet. These blue-face units are legendary for a reason—they offer massive clean headroom, a crushing low-end punch, and a distinct grit when pushed that you just can't replicate with modern gear. Whether you're running a guitar, a bass, or a heavy vintage synth setup, this rig is built to move serious air.

The Model 330 head features a highly versatile dual-channel preamp layout, a 5-band graphic equalizer to perfectly sculpt your frequencies, functional bright switches, and a lush built-in spring reverb tank. On the back, it retains its original power cord brackets and crisp labeling. Paired up with the Model 403 4x12 cabinet, this stack delivers an absolute wall of sound.

Cosmetically, this rig is one of the cleanest and well kept ACC stacks we've had in the shop, and presents the perfect amount of real-world mojo. Some light wear on the black Tolex, with clean front grille cloth showing off the four drivers beneath, and sturdy factory casters on the cab to save your back on the way to the stage. For a true touch of vintage road history, the back of the cabinet features a stenciled band name, "LOS PECADORES." It is a rock-solid, road-tested rig that is ready to anchor your backline.

Please view the photos closely for an accurate look at the cosmetic condition.
