Cornell Plexi 7 MK II
Cornell · amplifier
The Cornell Plexi 7 MK II is a 7-watt all-tube amplifier head from Cornell Amplification, a UK boutique builder. Based around the classic Marshall Plexi circuit topology at a fraction of the original power, it delivers authentic Plexi-style tones — open, harmonically rich clean tones and natural crunchy breakup — at volumes practical for home studio and small-venue use. Hand-wired point-to-point construction to vintage standards. The MK II designation reflects a refined revision of the original Cornell Plexi 7.
