The Battle Zone is a Killer Tube Pre-Amp

High Velocity Tube Tone is what you need when confronted with radical, extremist fans. This weapon is a proven killer on the battlefield, and your local music venue. Two 12a_7 tubes provide extreme Gain and Unbelievable Balls (short for Ballistics). Your fans will die in their tracks when they hear this bomb explode. Don't show up at your next gig with an Axe as your only Weapon.
