Kurt Cobain’s Marshall JCM800 Ampaccess_time First seen circa 1991
Kurt used this amp on a few occasions in June 1991, more precisely on June 17 at Crest Theatre, Sacramento, CA, and on June 14 at Hollywood Palladium, Los Angeles, CA.
It’s hard to tell from the photos, but the amp was either a JCM800 or a JCM900 model. 1991 was the last year that the Marshall made JCM 800 amps, and JCM 900 came out in 1990 – so it could’ve been both.
However, based on the fact that the input cable on Kurt’s amp was all the way to the right, JCM800 (Model 2210) is a more likely option (on a JCM900 it would’ve been closer to the middle).
