The VOX AC4TV8 guitar combo amp is s retro, it's chic, it's all-valve and it's all VOX. And the VOX AC4TV8 guitar combo amplifier offers up all-valve VOX tone at practice and recording volume levels!

The VOX AC4 appeared in 1961 as a compact 4-watt all-valve amp. The VOX AC4TV8 compact practice guitar combo amplifier features the classic combination of a 12AX7 valve in the modified preamp and an EL84 valve in the power amp.

The original VOX AC4 used the EF86 Preamp Pentode valve and an EL84 Power Pentode valve. These valves were fine for the 1950s guitarist, as there was no cascading preamp high gain stage. This meant the VOX AC4 amplifier would not overdrive well. VOX decided this circuit would not be suitable for the modern day guitarist, as now guitarists like to have the options of clean, crunch or saturated overdrive. Not a re-issue, the VOX AC4TV8 combo amp is an up-to-date rethinking of the valve circuit that matches today's needs. The power amp is single-ended a Class A circuit to deliver a wide variety of tones ranging from that clean British sound to distinctive VOX overdrive.

When an amplifier's output valves are passing current at all times, the amplifier is said to be biased in Class-A, like the VOX AC4TV8 guitar combo amp. Because the current is flowing at all times, an input signal causes the current to flow immediately to the speakers, and therefore the sound is very fast and responsive to playing dynamics. Single-ended circuitry, used in the VOX AC4TV8 combo amp, means neither side of the output circuit is referenced to ground. The full swing of the output voltage goes across the speaker. An efficient way to get high Sound Pressure Level output from a 4 watt valve amplifier.

In the past, the way to over-drive an amp for serious distortion was to raise the volume. The VOX AC4TV8 combo amplfier provides three levels of power attenuation: a full output 4-Watts, 1-Watt, and 1/10-Watts. Even at the minimum level of 1/10-Watts, the VOX AC4TV8 combo can provide great all-valve distortion. Enjoy your favorite overdriven tone even when playing or recording in your own room or late at night.

Other features include the 8-inch custom Celestion speaker, a 16-ohm speaker output jack for driving external speaker cabs like the VOX V412BN for even more powerful sound, and the retro TV Front styling from the 1958 VOX amp designs.
