RedBeaR Amplifiers is a line of hand-wired, all-tube guitar amplifiers designed by Russian engineer Sergei Novikov and built by Novik, Ltd. in St. Petersburg, Russia during the mid-1990s. The line was distributed in the United States through a partnership with Gibson Guitar Corporation, with some cabinets manufactured stateside, before the distribution arrangement ended around 1997–1998.

The amps are voiced in the vein of a hot-rodded Marshall JCM800, with a thick, aggressive high-gain character often compared to Soldano-style tones. Production centered on 60-watt and 120-watt variants offered as heads and combos, with matching speaker cabinets. Documented models include the MK60, MK120, MKX 50, and a variant labeled Red Bear Lead.

Because the amps were produced in relatively small numbers and for only a short window, they are uncommon on the used market and have a small but dedicated following among players who favor vintage Russian-built tube gear and high-gain rock and metal tones.

RedBeaR Amplifiers has 2 products cataloged on Equipboard, including Guitar Amplifier Heads and Guitar Amplifier Cabinets. Their gear is featured by 1 artist, with the strongest followings in Rock. Notable users include Micah Ortega.
