Vox AC30: The British Invasion Sound with Chime and Top-Boost
The AC30 is a legend. Its 30 watts with four EL84s and two 12-inch speakers produce the chiming, jangly sound that defined the British Invasion. The Top Boost channel adds presence that cuts through any mix. The AC30 delivers unique compression and harmonic complexity from its Class A power section. When pushed, it breaks into a rich, complex overdrive that feels alive. This is the sound of Brian May and The Edge.

The AC30 is heavy at 70 pounds but delivers a sound nothing else replicates.
