The AC30S1 Combo is inspired by the iconic Vox AC30, yet it is stripped down for simple and easy operation. Featuring a single channel that is based on the unique Top Boost of the AC30, the Vox AC30S1 yields the legendary tones of artists throughout the decades. The Vox AC30S1 Combo has an all-tube design, consisting of two 12AX7 pre-amp tubes and four EL84 tubes, for a full-bodied and well-rounded response. Equipped with a 12" Celestion speaker, the AC30S1 offers excellent projection for performances, rehearsals or practising. Other features include send/return jacks for connecting effects pedals, and an external speaker output for pairing with other speaker cabinets.
