The Vox AC30C2 amp makes use of three 12AX7 preamp tubes and use four EL84 tubes to deliver 30W of power. It uses two 12 in. Celestion G12M Greenback speakers, and includes a switchable 8/16 ohm output jack for powering an external speaker cabinet when you need to speak with a little more authority; using this jack will mute the internal speakers. Additionally, the 30W guitar amp's 2nd extension speaker jack allows you to run an extra 16-ohm cabinet along with the internal speakers for a fuller sound.
