Tech 21 Programmable Driver Amp Simulator/DI Bass Effects Pedal Description Always thinking of their fat-stringed brethren, Tech 21 had to make a 3-channel, programmable, rig-in-a-box for bassists who can’t get enough of a great thing. Like the TRI-A.C. for guitar, you get three hot tones right at your toetips. The all-analog circuitry features the same controls as its single channel predecessor: Drive, Bass, Treble, Presence, Blend and Level. Digital only in its programmability, you just tweak the knobs until you find a tone, double-tap on a footswitch, and it’s saved in that channel. It’s that simple. Three of your faves — to go! Features Build your Bass Driver DI into a live rig with a Bass Power Engine 60, and run through the PA for extra power.Boldly go live with just your Bass Driver DI straight into the PA.Bounce into any studio with a Programmable Bass Driver DI and plug directly into the board.Operable with a 9V alkaline battery or Tech 21 DC4-A power supply (not included), and it is also phantom powerable.Drive and DI Pedal for Bass Guitar3 Programmable PresetsFunctions as Stompbox or DI BoxPowerful EQ and Drive SectionsSimultaneous 1/4" and XLR Outputs48V Phantom Power CompatibleLow-Z Outputs for Long Cable RunsAll Analog Signal Path Attributes Color: BlackTechnical Specifications Effects: DI, Preamp, SimulatorProcessing Type: AnalogInputs: 1 x 1/4"Features: Battery-PoweredOutputs: 1 x 1/4", 1 x XLRPresets: 3 programmable presetsPower Source: 9V DC 100mA power supply (sold separately)Dimensions: 2.25" H x 7.25" W x 5.25" DWeight: 1.56 lbsBatteries: 1 x 9VEQ: 2-Band EQ, Prescence
