I'm playing a 1973 Marshall JMP 50W Lead half stack where I combine Greenbacks and Blackbacks. The warmth and spatial richness of the Greenbacks combined with the punch and presence of the Blackbacks results in one of the best tones I've ever had on the channel!
Someone told me there were some KZitemr falsely claiming that the difference between Greenback and Blackbacks is just the color of the cap. So, I provide you with the definition below. The three eras of G12M/G12H are actually quite different in tone.
The Celestion G12M and G12H (and others) used
Pulsonic Paper Cones until 1973 (Green)
R/C1 Paper Cones 1974-1975 (Cream)
Kurt Mueller Paper Cones 1976-1980 (Black)
The names refer to the color of caps most commonly occurring for each type.
There are other differences too regarding voice coil, doping etc but the cones is the main difference.
