The Markbass SD800 amp head is perfect for the times when you need speed and clarity at high volumes, especially in big-stage applications. This digital power amp delivers 750W of power into a 4 ohm cab or 450W into an 8 ohm cab. Recommended for use with big cabinets (8X10, 6X10, or 2X15), or two-cabinet rigs, this little solid-state head gives you plenty of headroom and has several options for protecting and shaping your sound, from its VLE (Vintage Loudspeaker Emulator) and VPF (Variable Pre-shape Filter) options to the Pre/Post EQ setting which allows you to choose whether your line out signal is affected by the amp's EQ. The SD800 Head has an input jack that can be used with either active or passive basses as well as dual Neutrik Speakon Combo jacks so you can connect to one or two speaker cabs using 1/4" speaker cables or Speakon cables.

Comments about Markbass SD800 750W Bass Head:

This little head is truly incredible. Plenty of power and tone variability for my ampeg 4x10. Does anything from vintage to modern. No issues whatsoever and it only weighs 8 lbs! This is the first Markbass product I have owned and I'm already amazed.
