Throw away your overdrive pedal and hurricane proof your windows! If you and your neighbors within a one mile radius love the sound of classic rock in its purest form, look no further than the 1975 Marshall Super Lead Mark II 100-watt (Model 1959) paired with a matching Marshall 4x12 stack.

This is the amp that defined stadium volume, punchy cleans, and legendary crunch when pushed. Plug straight in, crank it up, and you’re instantly in Page/Hendrix/Clapton/AC/DC territory. Loud, raw, and unmistakably Marshall.

This is a non–master volume Super Lead, built to be simple, powerful, and brutally honest. A true piece of British amplifier history that continues to set the benchmark for rock tones. The head and stack have not been modified other than a tune-up in 2022 to get it back to stadium-ready condition.

Overall Appearance & Cosmetics: this rig sat dormant in a suburban Detroit basement for nearly 50 years, shrouded in mystery under its factory-supplied black vinyl covers.

Hardware: the amp motherboard was lightly refurbished by Dean Zink (). Some of the “popcorn” electrical components from the 1970s needed to be replaced and resoldered, as did the tubes. See photo for more details.
