Flexible and feature rich bass amplifier with a large choice of sounds

14.08.2016
Good choice for aspiring bass players thanks to strong power amp and versatile pre-amp section and wide range (but not comprehensive) set of input/outputs.

I use the GK MB 500 to drive an 8 Ohm GK CX 115 cabinet. The pair works flawlessly and provides plenty of power and a wide range of sound settings. Ideal pair for an aspiring bass player in an electric band setting.

The MB 500 is a solid state amplifier in both pre-amp and power amp sections. The 4 channel EQ section is well designed and works well for sound shaping and adaptation to room acoustics. Furthermore, the contour dial is a real plus: once the EQ has been adapted to the room/stage acoustics, the contour dial is the best means of varying sound shapes between different musical styles. This is a real advantage in life settings: the bass player can concentrate on a single knob instead of fiddling around with all 4 EQ knobs.

A foot switch is included in the amp package. In a practical setting, you?ll use it to activate/deactivate the boost ?growl? effect and volume (master-b) pre-set during the sound check. The boost section is versatile: you can use it either to play clean at higher volumes (bass soloing) or to add both growl and volume ? useful for bassists of cover bands playing modern clean pop tunes and tube-amp growling 70?ies hard-rock in the same set.

Pros:
? flexibility of sound shaping thanks to effective 4-band EQ and additional contour
? foot switch for boost and ?growl? effect
? two speaker outs (no need to daisy chain cabinets)
? light weight

Cons:
? AUX/line-in missing
? speaker(s) must be disconnected to use headphone
? printed manual missing a page with recommended setting for different musical styles ? PDF download can be found on GK web pages (https://static1.squarespace.com/static/52d881e0e4b093afad1a2ae2/t/54a30912e4b04dcb56cd50eb/1419970834206/MB500-manual.pdf)

Lightweight, versatile, great sound!

HenkS, 12.02.2014
I bought this amp because I wanted to get rid of all the heavy stuff I had before, I use it together with a GK NEO 212 for 3 years now. It really sounds awesome for alternative rock that I play, it's always loud enough and the handling is just fun. It weighs almost nothing (so does the 212) and can be carried to rehearsals in a gig bag together with the bass guitar. It sounds a bit more clean than the 700rb I had before but still definitely like a gk amp. When using higher gain settings or the boost channel, it can also give you very good overdrive sounds, not really ampeg-like but more "modern" I'd say. Only downside: If you plan to use both channels together with D.I. out on stage, you can not adjust the D.I. volumes of both channels independently (see the block diagram in the manual)
