The JCM25/50 Silver Jubilee Series was produced in 1987 to celebrate 25 years of Marshall Amplification and 50 years of Jim Marshall being in the music business.

The 20-watt 2525 Mini Jubilee is expertly crafted and is designed, engineered and constructed to the highest possible standards at the Marshall factory in Bletchley, England. It shares the original Jubilee Series features, as well as High/Low output switching (20 watts to 5 watts) and independent 4/8/16 ohm speaker outputs.
