Ampeg Venture V3 300w Bass Head

Here's what Ampeg say about the Ampeg Venture V3 300w Bass Head:

"The ultra-portable 300-watt Venture V3 is the smallest and lightest of the three heads in the Venture Series and easily fits into a gig bag, a laptop bag, or the optional Venture carrying bag, making it an excellent choice 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 while touring.

• 300 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
• 3.97lb / 1.80kg

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 center position bypasses the Ultra Lo circuit.

Ultra Hi

This 2-way switch engages a 9dB boost at 8kHz.

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).

Power/Mute Indicator

This LED bar lights up blue when the amplifier is powered on and red when the Mute switch [14] is engaged.

DI Bal. Out

This balanced XLR output may be used to route line-level audio to the input of an external mixer or recorder, or to an external power amplifier or powered loudspeaker. It is not affected by the Volume control.

• Pre/Post: When set to Pre the DI signal bypasses the -15dB input pad, Compressor, tone controls, SGT circuit, and FX Loop. When set to Post it includes them.
• -20dB: Reduces the DI output level by 20dB.
• Lift/Gnd: Engages the ground lift to help eliminate hum if necessary.

Switch (TRS)

Connect a 1/4" TRS dual footswitch to remotely toggle the SGT circuit (tip) and Mute (ring) on and off. Connecting a TS single footswitch will toggle the SGT circuit on and off."
