The LMK is the only 2-channel bass amp head made by Markbass. The LMK bass amp is designed for maximum flexibility with a unique design that allows you to set up different tone, filter, and volume setting for two separate basses (electric and acoustic). You can also use the Markbass LMK to combine two different sound sources from one instrument, or use the amp to magnify your bass along with an auxiliary input such as a drum machine or sequencer with complete control of each input. Each input has a 4-band EQ, Markbass' VPF (Vintage Pre-shape Filter) and level control - with the master adding a (Vintage Loudspeaker Emulator) filters and over Master volume knob.

On the LMK bass amp's 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.
