The addition of a second speaker enhances the classic VOX tone.Introducing the new AC15C2 TWIN. The Custom Series AC15 amplifier is now available with two 12 Celestion G12M Greenback Speakers. This new AC15C2 TWIN (as it was affectionately referred to in the 60\'s) enhances the full, chimey sound of the traditional AC15C1; and also features the larger spring reverb tank found in the AC30C2.Based on the classic AC15, the AC15C2 TWIN is part of the VOX Custom Series line. These amps have been updated to include dual channel sound, tremolo circuitry, and footswitching capabilities. True to its past, the AC15C2 TWIN relies on 3 x 12AX7 dual triode vacuum tubes in the pre-amp stage, and 2 x 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 in between.The AC15C2 TWIN provides the VOX Classic Tremolo effect, with adjustable controls for both the speed and the depth. A warm Spring Reverb is also included on all Custom Series amps, adding spaciousness to the sound. Thanks to the AC15C2 TWIN s two-speaker cabinet size, the AC15C2 TWIN uses the larger reverb tank found on the Custom Series AC30 modelsThe optional VFS2 footswitch provides a hands-free method for turning the Reverb and Tremolo effects on and off while performing.
