The Ampeg V-2 preamp schematic covers the preamplifier section of the V-2 guitar head, which featured a two-channel design with 12AX7 preamp tubes providing clean and lead voicings. The V-2 preamp offered a selectable bright switch and mid-focused tone stack characteristic of early 1970s Ampeg guitar amplifier design. As part of the V-series line, the V-2 preamp shared design philosophy with the larger V-4 and V-9 models, scaling the circuit for a 60-watt output stage.
