Make the walls shake, rattle, and roll.

Markbass knows that some bassists need more than 1000W of power. That's why the SD 1200 bass amp head was created. Headroom is all about having more power than you normally need, and this mighty amplifier will allow any bass player in any band to hold their own, no matter how big the stage or how loud the band. The Vintage Loudspeaker Emulator (VLE) and Variable Preshape Filter (VPF) allow access to a wide array of timbres, from classic tones to modern hi-fi. The Markbass amp head's sound is exceptionally warm and clear even at full volume, providing ultrafast response and unparalleled reproduction of the most minute details of your playing.

    Comments about Markbass SD 1200 Bass Amp Head:

    Great Amp.More power than one will ever need.This amp has plenty of power and oomph.Powers my 410 Swr Golite,800 watts at 4 ohms with ease.I like that the eq section is plenty basic without a 100 different knobs.For the price point,1200 watts is a lot.Amps a little wide,but not that much,but light as can be.I like that they supply you rack ears.One the best solid state amps out there,unless you want to go boutique and spend more
