This little Vox AC-4 amp, the smallest of the JMI line, is one of the sweetest sounding 60's Vox amps we have had in a long while. These were designed as a student amp but in our lower-volume environment today are far more useful than simply as a practice amp. In the mid-60s the Beatles took one of these little babies on tour for use in their dressing rooms!

The AC-4's top/rear-mounted control panel features two inputs, a volume control, a speed control for the tremolo and a combined tone and on/off switch. It has the same cosmetics as the larger period Vox amps including the gold-and-white piped black covering, molded plastic top vents and diamond checked grille cloth. Running a single EL84 into an 8" speaker, The AC-4 puts out somewhere around 6-watts. Topping out at Champ-like volume when cranked, it is incredibly touch sensitive, responsive and simply great fun to play.

The outer covering shows some very light wear and a few small edge tears; it is a bit dirty overall but only minimally damaged. The JMI ID plate on the back is in good shape, save for a few light scrape-marks. The copper control panel enamel has a few marks including one long scratch, but looks spiffy nonetheless and retains all the stenciled lettering. The handle mounts are somewhat corroded.

Electrically, the little amp is nicely original and just as the gods (and the boffins at Jennings Musical Industries) made it. The original 8" Elac speaker has been professionally reconed and sounds great. The transformers and the pots are all original. The amp has received our routine maintenance, including replacement of all electrolytics, the installation of a 3-prong power cord and cleaning of all sockets, pots and jacks. This AC-4 has a pin-mounted voltage selector and must be set to 110V to operate properly on US line voltage; fortunately this is almost impossible to change except on purpose. The original tremolo footswitch is still intact and working and the amp includes a red vinyl slip-cover, which we suspect is a later addition, but nonetheless cool looking.

The perfect tabletop or home recording amp, this is one of the coolest little JMI-made amps we have had of late and a joy even to just look at. Plugging into it takes you back to the British Invasion vibe of 1964, especially with the period Gretsch, Gibson or shadows approved Stratocaster! Overall Excellent Condition.
