Lots of THIS. After all the stock and modded JMPs and 800s, Jubilees I finally bought a totally stock early 70s SuperTremolo. I've owned a few similar JMPs but every one had a MV mod. Honestly, I wish I had bought one totally stock YEARS ago....I would have saved a ton of cash. None of the stock or modded 800s, or modded JMPs (I've had over 50 at this point by most of the known Marshall modders) can touch this 72' tone with just a couple pedals (cheap, less than 100 bucks for both) in front. Not even the Wizard MCI I had sounds as good as this Marshall, for what I like anyway. Now I know why guys loved using these amps with just a pedal or two, cranked. Tone of the Gods.
My desert Island amp, over anything I've owned including Wizards, C+, Camerons, Triple F, Naylor, SLO, anything.
It's the one that will remain if I decide to sell most of my gear.
