The VOX Custom Series AC15 guitar combo amp is now available with two 12" Celestion G12M Greenback speakers. This "TWIN" enhances the full, "chimey" sound of the AC15C1; and also features the larger spring reverb tank found in the AC30C2. The Custom Series have been updated to include dual channel sound, tremolo circuitry, and footswitching capabilities. True to its past, the AC15C2 "TWIN" relies on three 12AX7 dual triode vacuum tubes in the pre-amp stage, and two EL84 pentode tubes in the power stage.

Two channels are provided on the AC15C2: Normal and Top Boost. Each channel is equipped with its own Volume control, and the Top Boost channel offers highly interactive Treble and Bass tone controls. This powerful channel pairing provides an abundance of tone-crafting control. Both channels rely on the Tone Cut and Volume controls in the Master section. The Tone Cut control operates in the power stage rather than the preamp stage, allowing an additional degree of tone shaping. The Master Volume control works in conjunction with the individual volumes of each channel to create just the right degree of gain-staging. By balancing the individual and Master volumes, the AC15C2 "TWIN" can deliver the coveted clean VOX "chimey" sound or a powerful overdriven tone - and everything between.

The AC15C2 "TWIN" provides the VOX Classic Tremolo effect, with adjustable controls for both the speed and depth. A Warm Spring Reverb is also included on all Custom Series amps, adding spaciousness to the sound. The optional VFS2 footswitch provides a hands-free method of turning the Reverb and Tremolo effects on and off while performing.
