The Bugera 1990 Infinium is a 120-watt tube amplifier head from Bugera, Behringer's budget tube amp sub-brand, modeled on classic Marshall Super Lead circuit topology. It features Bugera's Infinium tube life multiplier technology, which claims to extend power tube life by constantly monitoring and adjusting bias. At its price point, the 1990 offered players a genuine EL34-powered Marshall-inspired experience.
