The Univox 1246 is the most powerful model in the 1200 series, delivering approximately 50–60 watts through an EL34 push-pull power section in a large combo or piggyback cabinet. Its circuit provides a full complement of tone controls, reverb, and tremolo, along with high- and low-gain inputs per channel for dynamic range accommodation. The British voicing — prominent mids, a singing treble, and a defined low end — makes the 1246 suitable for blues, rock, and country applications. It represents Univox's peak capability within the 1200 series and is an underappreciated vintage amp in collector circles.
