MicroBass Series III
A longtime favourite for some of the biggest session artists in the industry, GK’s MicroBass remains the standard for high quality compact bass amplification in and out of the studio. The MB Series III improves on its predecessor with greater signal to noise ratio (-90 dB) and cooler, more efficient operation. In addition to the ever popular Combo version, this little tone giant is now available as a 150 watt pocket sized head that can be paired up with the cabinet of your choice. Try it with GK’s 112MBX or the horn loaded NEO 112 extension cabinet. With its sturdy, welded aluminium chassis, the MicroBass Series III is equally at home on the road or in the studio.
