After the demise of JMI in 1967/1968, this short-lived version of the Vox AC-30 Top Boost amplifier (and the "VSEL" company in general, which declared bankruptcy just 2 years after inception) sports some different cosmetics compared to the classic AC-30/6 Top Boost amps of years prior, though they electronically remained essentially identical to the most heralded Vox amps.
