Solid-state 480W/4Ohm amplifier head for electric guitar from RB series that features unique horn bi-amp system which sends the high frequencies to the horn through a separate 50W amplifier. This has many advantages: the horn level is controlled from the front panel and the horn itself is not overpowered by the larger amp so failures are reduced. When the woofer amp hits the rails (growl) the horn stays clean. The amplifier features a dual-rail analogue power amp and power supply for classic feel and hard hitting punch, plus a toroidal transformer that provides the current required to control the speakers at high volume. It provides a 4-band active EQ and voicing filters based on the classic 800RB provide extensive tone shaping capability, Boost control which adds tube like harmonics and signature "GK growl" using G.I.V.E. technology, balanced DI with level control, Pre/Post and Ground Lift switches to feed the unit, tuner output, FX loop for connecting outboard accessories on the front, and two 6.3mm speaker jacks and two twist lock speaker connectors to ensure reliable and safe cabinet connections, mounted in the rear. Heavy duty chassis, large toroidal transformer and double sided boards ensure stable performance under the most rigorous tour conditions. Dimensions: 482.6 x 203.2 x 88.9 mm. Weight: 8.85 kg.
