The firm price you see is for the amp head only. This is an incredible find for serious collectors and tone purists alike, combining museum-quality authenticity with a fascinating connection to rock royalty. It's amazing this has not sold yet with over 1000 Views and Many saves it's an amp you have been dying to have and you look you save without purchasing?

What's that about they should call it the Dream List not the Watch or Save list. Are you a Dreamer or do you want to get down and busy with the best possible amp on planet Earth. Live your Dream and Rock on!

As a quick confirmation of its authenticity, your serial number SL/A 00064J is a perfect textbook match. In Marshall’s classic system, SL/A stands for the 100-Watt Super Lead circuit, while the suffix letter J definitively confirms the year of manufacture as 1977.

Regarding your question about Joe Walsh: given that the amp came directly from the relatives of Brad—the late best friend of Joe Walsh’s tech—and was preserved alongside a fully autographed James Gang CD, there is a highly compelling case for its provenance. While it would require documented inventory manifests from the tour crew to prove 100% that Joe plugged into this exact head on stage, the direct lineage to his inner circle makes it an extraordinary piece of rock 'n' roll history.

Here is your comprehensive, high-conversion listing ready for platforms like Reverb or eBay:

FOR SALE: 1977 Marshall JMP Super Lead MKII 100W Head (Original & Unmodded) + Optional 1996 V3412 Cab

Letting go of my absolute prize amplifier. The firm price listed is for the Amp Head Only. May the best man win!

This is a beautiful, meticulously cared-for, 100% stock 1977 Marshall JMP 1959 Super Lead MKII. Amplifiers from this transitional JMP era (1976–1981) are legendary for trading the fragile Plexiglas front panels for heavy-duty brushed gold aluminum. They deliver massive high-volume headroom and the definitive, aggressive classic rock "crunch" famously weaponized by AC/DC and Van Halen. Everything works flawlessly with absolutely no issues.

The Provenance & Backstory

This amplifier carries incredible rock 'n' roll DNA. It originally belonged to Brad, the best friend of Joe Walsh’s personal guitar technician. Following his passing, the gear was left to his relatives, from whom I acquired it. Included with the sale is an original CD signed by all members of The James Gang, including Joe Walsh, which was preserved right alongside the amp. Could this be one of Joe's original circle of amps? The connection is undeniable.
