This powerhouse bass combo brings the legendary 800RB tone shaping to a portable 38lb package that's built to handle everything from bedroom practice to moderate-sized gigs. The four-band active EQ and contour controls inherited from the iconic 800RB offer extensive sonic sculpting capabilities, with a unique design that varies the EQ bandwidth to maintain musical response even when pushed to extreme settings.
At the heart of this combo lies a custom-designed speaker featuring a 2.5 inch edge wound aluminium voice coil, manufactured right here in the GK USA factory. The plywood construction includes internal bracing to eliminate tone-robbing sound leakage through the cabinet walls, while specially tuned ports work alongside a specific jute blend damping material to provide optimal frequency response and performance.
The switch mode power supply and amplifier section pump out 200 watts with minimal heat dissipation, all housed within an aluminium chassis that's built to last. Tough vinyl covering with protective metal corners ensures this combo can handle the rigours of regular transport, while internal circuitry constantly monitors for potential issues, indicated through the power switch ring.
Professional connectivity options include a balanced DI with pre/post switch, auxiliary input for backing tracks, headphone output for silent practice sessions, and "chain out" capability to drive additional GK MBP powered enclosures like the matching 115 MBP for expanded sound reinforcement when needed.
