The Markbass Little Mark 250 bass amp head is a high-quality bass amplifier with a solid-state preamp and an analog power amp. The Little Mark 250 delivers 250W of power into a 4 ohm cabinet, or 150W into an 8 ohm cabinet. This Little Mark has a 4-band EQ, Markbass' VLE (Vintage Loudspeaker Emulator) and VPF (Variable Pre-shape Filter) filters, as well as both Gain and Master volume controls. The front panel accepts both a passive or active bass 1/4" input, as well as a balanced XLR input for acoustic bass pickup systems or a microphone. On the rear panel you'll find a Neutrik Speakon combo jack output that accepts both Speakon or 1/4" speaker cable as well as a second 1/4" speaker out jack. You'll also find a balanced XLR out, unbalanced tuner out so you can tune as you play without passing your signal through pedals, and a Send and Return Effect loop which saves you from losing your signal if one of your pedals dies or a cable in the chain gives out.
