The Vox VC-12 starts with the same capabilities of the VC-4 Foot Controller, such as Program Selection, Tap Tempo, built-in Tuner (with Mute function), Individual Effects On/Off selection, Wah pedal (that can also control Volume), external Volume pedal input, and Parameter Control. It also offers a second Controller pedal for Volume. Both pedals are heavy duty, chrome topped, the same as VOX Wah pedals. Large, heavy duty stomp box switches, independent Bank Up/Down switches, and a Recall switch automatically reverts to the prior selected program. In addition, the VC-12 is capable of storing four banks of Valvetronix amp user programs. Valvetronix amps alone can store 32 programs, whereas the VC-12 offers the user an additional 96 programs for a total of 128. Programs can be stored from any Valvetronix amp into the VC-12, and loaded into another amp. As an added bonus, the VC-12 can control two Valvetronix amplifiers at one time.
