Ampeg Venture Bass 1200w Head

Here is what Ampeg say about the Ampeg Venture V12 1200W Bass Head:

“The 1200-watt Venture V12 is the largest and most powerful of the three heads in the Venture Series, yet it weighs less than nine pounds and fits into a gig bag or the optional Venture carrying bag, making it an ideal head for the travelling bassist. Its Class D power section provides more than enough power to drive any of the Venture Series speaker cabs or practically any other cab bassists may encounter on their travels.”

Specifications

• 1200 watts @ 4 ohms
• Legacy Preamp with 3-band EQ
• Sweepable mid frequencies
• Ultra Hi/3-way Ultra Lo switches
• Footswitchable SGT Overdrive circuit with SVT and B15 voicing switch
• Variable Compressor
• 4lb / 3.8kg
• 0 dB/-15 dB Switch: Use this switch to set the optimal input level. Typically, youll want to use the -15 dB setting with instruments that include high-output pickups or active electronics, or if you frequently see the Peak LED [13] light up.
• Ultra Lo: This 3-way switch selects a -20dB cut at 40Hz (left) or a 2dB boost at 40Hz combined with a -10dB cut at 500Hz (right). The centre position bypasses the Ultra Lo circuit.
• Ultra Hi: This 2-way switch engages a 9dB boost at 8kHz.
• Peak: This LED lights when your input signal is too high.
• Mute: Engaging this switch mutes the Speaker outputs, the FX Loop Send, the DI output, and Preamp output. The Aux In signal at the Phones output is not muted. Mute may also be toggled on and off using an optional footswitch connected to the Switch jack on the rear panel. The Power/Mute Indicator LED [5] illuminates red when Mute is engaged.
• Input: Connect a passive or active instrument to this 1/4" jack.
• Compressor: This knob controls both the compression threshold and the compression ratio (up to 10:1 maximum). Turn it clockwise to increase compression, and fully counter-clockwise to turn the compressor off. The LED at the left lights to indicate whenever your input level exceeds the compressor's threshold and gain reduction is applied.
• Super Grit Technology (SGT) Section: Adds classic Ampeg overdrive.
• On/Off: Enables or disables the SGT circuit. The SGT circuit may also be toggled on and off using an optional footswitch connected to the Switch jack on the rear panel. (Note that connecting a footswitch disables the front panel switch.)
• SVT/B15: This switch toggles between two flavours of overdrive, based on the character of either the SVT or Portaflex B15 tube amplifiers.
• Grit/Level: This dual-concentric knob adjusts the amount of grit (the inner control) and the overall output level of the circuit (the outer control).
• Gain: Adjusts the signal level driving the preamplifier.
• Bass: Provides up to 13dB of boost or -21dB of cut at 40Hz (flat at centre position)
• Mid/Freq: This dual-concentric knob selects the midrange frequency to be boosted (the outer control), and the amount of boost or cut up to 16dB (the inner control).
• Treble: Provides up to 12dB of boost or -16dB of cut at 4kHz (flat at centre position)
• Volume: Adjusts the overall output level of the Speaker, Phones, and Preamp outputs.
• This brand new head uses the new Neutrix NL2 Speakon Plugs
