Read the current issue of VG. All used four A output tubes to generate a conservatively rated watts, which can often top watts downhill with a good tailwind… which is to say, when cranked. And though we say this was a rock-intended amp, it was rock as Ampeg intended it — bold, punchy, clear, and ungodly loud. Who could use such an amp today? Perhaps fewer players than back in the day, but, back when it was introduced, it proved to be exactly what plenty of touring pros required, most notably the Rolling Stones.
More accurately, the Stones acquired several prototype SVT bass amps and cabs and, later, several VT amps rather urgently while rehearsing for that tour, after their own amps failed at the hands of U. As such, the band served as beta testers for the new designs. The V Series Ampegs were designed by Dennis Kager, and remain very much within the Ampeg ethos — or, perhaps more accurately, represent an extension and enlargement of that ethos.
This individuality is seen in a plethora of oddball tubes employed in the circuit, and some extremely versatile frequency-shaping capabilities in its tone stack and unique sensitivity and voicing switches. After a couple of gain stages each provided by the two triodes of a 12DW7 in channel 1 and a 12AX7 in channel 2 respectively, the treble and bass pots are sandwiched between two more gain stages provided by a second 12DW7, with the midrange control and related three-way frequency switch brought in after that stage, before a quirky 6K11 tube a triple triode, meaning it contains three individual amplification stages used as gain recovery.
A 6CG7 tube serves as reverb driver, while the second half of that third 12DW7 drives a 12AU7 phase inverter into the big A output tubes. For all this, a vintage VT is not a particularly expensive amp on the used market.
