The Vox AC30S1 is a one-channel full-tube combo that turns out to be the ideal guitar amplifier for purist rockers and pedalboard lovers. Based on the legendary "Top Boost" channel with two 12AX7 tubes, it delivers an incredibly vivid sound that can be increased from glittering clean sound to juicy overdrive with the help of the gain control. The 2-band tone control allows the sound character to be adjusted, while the reverb effect provides a vivid three-dimensionality. With 30 Watt power output from four EL84 tubes and a 12" Celestion VX12 custom speaker, the Vox AC30S1 Combo delivers a particularly powerful sound with surprisingly high volume reserves.
