    Classic VTBP-201 tube pre-amp circuitry . Hand wired in the USA using High quality components, DC filament, full 220V high voltage supply. Passive tube tone controls Treble, Middle, Bass and Presence. Our new Mode switch that lets you control the overall tone: Dark, Normal and Bright. It also includes active and Passive inputs. The unit has a pre-amp output if you need to run more power amplifiers (like our Minnie 800D) and a power Amp input. The power Amplifier delivers 250 Watts RMS into 8 ohms and 400 watts RMS into 4 ohms There are two Speakon combo jacks on the back to hook up your speakers. The unit comes stock with a line level Balanced studio out that is selectable Pre or Post EQ. We also offer an upgrade for the studio out using a Jensen transformer microphone level Direct output. The Amplifier comes in a Black Tolex covered birch plywood cabinet with handle. The amp weighs only 8 lbs and measures 11”wide x 5.5”high x 8.5”deep. Built right here in the USA in our Barn in Templeton CA.

    • Inputs: two instrument level 1/4” jack. One for Active Basses and one for Passive Basses
