The Markbass Multiamp is the bass version of something guitarists have enjoyed for years, like an Eleven rack or Axe FX specifically for bass. The Markbass Multiamp features a poweramp so you can use it as your live rig, as well as being a recording device for the studio. The advantage of any device like this is that you can set up multiple sounds for solos, set up sounds for individual songs, and take the sounds you record on an album, or spend time tweaking at home, to the stage. Like all Markbass products the Markbass Multiamp feels like a quality piece of gear that would stand up to years of abuse on the road.

The Markbass Multiamp can do a lot and seems a bit daunting at first, but it is very easy to navigate and get up and running, without the need for reading pages of user manuals. Navigation through the unit is very intuitive and easy to do via the large front panel display. The single input jack features a pad button for active or passive electronics. Once you have selected the input level you can choose between three different amp models based on amps in the Markbass range, and a few classic amps renamed to suggest what they are trying to emulate. Built into the unit are 105 factory presets to get you up and running fast. You have a four band EQ, the same as you would have on a traditional amp, allowing you to tweak the EQ very quickly without the need to navigate through the screen display. With the EQ controls on the outside of the unit you have a bass processor that feels much like a traditional amp.

For quiet practice situations you have a headphone output with an individual level control independent of the master volume control. The back panel of the unit features both a speaker output in the form of a speakon and jack connections, as well as a DI section sending the full cabinet and effect emulations. You also have the option of midi connectivity, so you can change channels and switch effects on and off via any midi pedal controller. There is a USB port so you can service the unit or update the software, and it appears that Markbass will continue to update and refine the software over time.

Programing your own patches is very easy. You get a choice of eight different cabinet emulations; all based on different Markbass cabinets. Once you have selected the cabinet you can change the microphones in front of the cab, as well as the position of the microphone. There is a reprise function that allows you to adjust the cabinet’s ambience and resonance. There are both high and low frequency limiters, which can limit just the lows or just the highs of your signal. You can also flip the phase of your signal if there are any phase problems when recording.You can add many different stompbox style effects to your signal path and the Markbass Multiamp contains fifteen inbuilt effects, everything a bass player could possibly need. There are distortion effects, chorus, phaser, reverb, delay, volume, noise suppressor, parametric EQ, octave, synth, compressor and envelope filter effects. If that’s not enough, or there is a pedal you just can’t do without, then there’s an effect send and return that you can use.

THE BOTTOM LINE
The Markbass Multiamp really is an all in one unit for bass players both in a studio and live performance setting. The tones are fantastic emulations of Markbass sounds plus a few amps that would be considered recording staples. The output options, plus the effects loop, give you enough flexibility for any playing situation – bass players now have the same all in one unit that guitarists have enjoyed for years.
