My 1959 Marshall stack which was made around 1969 with Celestion G12M 20 watt Pre-Rolas. I made the big mistake of having to sell it for something smaller as I had joined a band cross country and needed something smaller to fit in my car which ended up being a Mesa Boogie MkIII Head and 2 smaller Boogie cabs. They did not sound anything close to my Marshall stack and I long to have that amp again. What I big mistake I made selling the Marshall! The band broke up as soon as I arrived which added salt to the wound.
