The Vox AC15 Custom Amplifier Head is a brand new addition to Vox?s line up of popular AC amplifiers. Loaded with all sought after features from the original AC15 combo amplifiers the AC15 amp head also includes switchable output impedance and wattage attenuator perfect for low volume practise. With an output of 15 watts all valve configuration dual input channels (normal & top boost) and on board reverb and tremolo effects the AC15 Custom Amp Head is perfect for performing musicians. VOX Custom Series amps offer two channels: 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 letting you dial in a classic sound that is all your own. 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 Custom Series can deliver everything from a clean VOX “chimey” sound to a powerful overdriven tone. Sound in Motion You can sweeten the sound of your Custom Series amplifier using the VOX Classic Tremolo effect. Both the speed and the depth are adjustable allowing you to generate just the sound you want. A warm Spring Reverb is also included on all Custom Series amps adding spaciousness to the sound. The AC15 also includes an additional tone control in the Reverb section. All Custom Series amps can use the VOX VFS2 footswitch allowing you to turn the Reverb and Tremolo effects on and off as you continue to play. Switchable Impedance and Wattage The Vox AC15 Custom includes two 1/4 inch speaker outputs for connecting to single or multiple speaker cabinets simultaneously. Furthermore with a selectable output impedance of 8 or 16 ohms the AC15 is compatible with a range of speaker cabinets. In addition the AC15 also incorporates a selectable output wattage of 1/6 1.5 and 15 watts to allow provide premium driven valve tones even at low volumes.
