Markbass LMK 58R

Historical Context and Positioning in the Range

The LMK is part of those Markbass heads that have become references for bassists seeking a compact, reliable, and effective live format. With the LMK 58R, Markbass brings back this "classic" spirit on a more modern MB58R platform, focused on practicality: all controls on the front panel, featherweight, and a decidedly modern approach to sound management thanks to its two channels and mix mode.

Who This Amp Is For

The Markbass LMK 58R is aimed at intermediate to professional bassists who need a head that is easy to transport but powerful enough to cover rehearsals, studio, and gigs (small to medium venues, or large ones via the XLR output to the PA). Its dual-channel concept is perfect if you switch between two instruments (for example, a passive and an active bass) or if you want to instantly switch from a groove sound to a more percussive tone (slap, featured parts, more saturated passages via gain).

It is especially recommended for styles where the bass must remain clear and controlled: funk, pop, rock, fusion, gospel, and any playing situation where you need to keep a solid foundation while changing character on demand.

Features and Innovations

The LMK 58R focuses on a very "musician-friendly" workflow: two independent channels with a dedicated input per channel, and a switchable Input 1 to quickly assign your instrument to the desired channel. Each channel has its own gain and full EQ, allowing fine balancing of level and tone without relying on external pedals. The front panel channel switch includes a "mix" position to blend both channels, opening the door to richer textures (for example, one channel rounder and one channel snappier, combined depending on the context).

For level control, you have a MASTER for the main output, as well as a Line out adjustment. The head also features a new Bi-band limiter, designed to maintain clean and controlled lows while preserving attack and dynamics in the upper spectrum, particularly useful when playing loudly or with very expressive technique.

Sound

The Markbass LMK 58R is designed to deliver a clean, direct bass sound that sits easily in the mix. The two channels allow switching from a wide, balanced clean tone to a more biting setting simply by changing channels or using mix mode. The 4-band EQ per channel provides real control over the low end (for foundation), mids (for presence and clarity), and highs (for attack), while the "shape" switch offers a more modern voicing with scooped mids, ideal for more "hi-fi," slap, or pop sounds.

Thanks to its power reserve, the LMK 58R maintains good headroom and controlled response, helping to keep notes firm and articulated even when the drummer pushes hard. Live, the XLR output simplifies soundchecks, and the whole unit remains coherent: a head designed to sound effective, straightforward, with immediate control from the front panel.
