RB Series Bass Heads
GK’s RB Series bass amplifiers have been setting the standard for over two decades. Inside these compact, lightweight ‘superstructures’ is the most advanced bass circuitry available. In 1972, Bob Gallien developed what he calls G.I.V.E. Technology (Gate Induced Valve Effect). This ‘valve effect’ is integrated into the design of all RB Series heads and is part of what gives them their distinct sound.

Backline amplifiers are built using the same quality components as GK's professional products including a high current power supply for maximum punch and toroidal transformers for greater efficiency. This is no budget bass rig. The Backline Series is the real deal... They just happen to cost less.RRP.$599.00

The MBX series enclosures feature GK’s Paragon ceramic magnet loudspeakers, piezo tweeter, plywood construction, Tolex covering, recessed spring loaded handles, rugged steel grills, and custom interlocking corners. Speakon and 1/4” inputs are provided as well as a tweeter defeat button. All models utilize porting and substantial bracing for optimum bass response and clarity.

Weighing in at less than 4 lbs. and taking up less than one rack space, the MB delivers 500 watts of power in a package that will easily fit into your gig bag. Featuring GK’s legendary four-band active EQ and contour control, the MB500 allows you to tweak your tone before hitting the digital power section. In addition to the generous tone shaping capabilities, the preamp section also features a footswitchable boost channel with independent volume control to dial in just the right amount of grind and level boost when needed.
