The Groove Bass 600HD captures the essence of the classic Groove Bass sound and presents it at a price that most any bass player can afford. Rated at 600 RMS watts, the Groove 600HD packs a mighty punch and provides all Groove Bass 1300HD features with the exception of the EQ Shift switches. Other popular Groove features such as the 9-Band Active EQ, Effects Loop, Neutrik® Speak-On output connectors, Pre- or Post-EQ XLR Line Out, Tuner Out and Solo Boost functions remain untouched. The footswitchable Mute function, which allows players to silence their amplifier rig while tuning up, now activates a blinking LED to make the Mute mode more noticeable on dark concert stages.
