Built on a two-channel design with normal and bright/high gain inputs and bringing in features like a three-band EQ, presence control, and vicious Tung-Sol power and preamp tubes, the Electro-Harmonix MIG-50 amp head recreates the power of an original workhorse in a contemporary package. Made to not just emulate the cult favorite Sovtek MIG-50, the modern EHX model improves upon its predecessor with higher-grade components and a hand-built construction made to deliver powerful, reliable performance for years.
