This is a new AMT VtE-1 VT-Drive. No battery or power supply. Original box and manual is included. Will run off a 9v adapter or 9v battery.
"The AMT Vt-DRIVE was designed for guitarists looking for distoriton sounds similar to that of VHT* amplifiers. When using Drive Series Effects, the resulting sound is mainly influenced by the combo or amplifier you use, as well as the speakers installed in your cabinet. The Drive Series were designed for guitarists who do not need or desire the speaker emulation of the Legend Amp Series. Drive Series pedals provide massive gain, and tonal perfection; just as the tube heads they represent!"
