First introduced to the US market in the late 2006, the AD100VTH head was the loudest member of the AD Valvetronix "Chrome" series of amplifiers. Vox offered the V412BK 4x12 enclosure to accompany this amp head.
The AD100VTH control panel was loaded with controls for eleven amp models, eleven pedal effects and a two channel digital programmer. An optional VFS2 floor pedal allows for remote control of stored tonal programs.
The V412BK featured four 12" Vox special design speakers in a closed back, pressed board cabinet with plain black grill cloth.
The AD100VTH is a very loud amp, but a rear panel power amp level control allows you to reduce the output power of the AD100VTH all the way from 100 watts to one watt.
