Okay, I'll admit... I bought this '1992 Marshall JCM 900 100 Watt High Gain Dual Reverb' for nostalgic reasons. This amp was my very first Marshall I bought 30 (!) years ago when I just started performing with my first band 'Blues on the Road'. I also still own the 'Marquis 4X12' I was playing back then. You can find that one on this page also. As for the JCM 900 sound; the gain channel goes to 20. So... That's 10 louder, isn't it!? To my surpise the clean channel is great, so I will be using that and let my trusted old Boss SD-1 do the heavy lifting.
