This one gets my pick for Marshall's MASTERPIECE guitar amplifier. This example has had a giant HOLE drilled in the side of the cabinet for a 120V fan. The owner is complaining of a strange sound like a blown speaker. We'll see if we can duplicate that problem and give this one a full service and repair.

I have this exact amp in fawn tolex. I bought it from an older lady who had bought it for her son when he was 18 years old. He passed away about 10 years ago and she sold it to me. It literally looks brand new. He played it at church, believe that, or not. It has the original Marshall 4X12. It is all original including the speakers in the cab. No mods. It is a fire breather. Great to see you on here, brother!

In 1983 I bought one of these in a twin combo form in fawn color tolex(pretty rare). It was a 1977 model also. I paid $400 for it used for at Deitze music house in Lincoln, NE. I rocked it using a Tom Sholz power soak and we played 4 nights a week for 7 years. It never missed a lick, such a great amp it was. My biggest gigs were opening for the band Head East, also got to open for comedian Joe Piscopo, and the biggest was opening for Billy Squier at a outdoor Festival. Anyway I love this amp too. I sold it to my cousin around 1992 and he still has it today! I want it back, but he wont sell it. Nice job with this amp and also your playing on this one was awesome! Thanks Brad and take care!

@Johnsormani 9 месяцев назад

My first amp. Bought it in 1980 when I was 16. Still have it to this day. Completely stock. Also have the same as a combo. Great amps

@RelicOnMaui 9 месяцев назад

I cannot believe I traded my 100 stack for a Les Paul Standard and some ca$h at Sol Betnum's (Anyone remember that HOUSE with its rooms filled with used music equipment?). But I was never able to play the thing anywhere besides my parent's home without the LAPD or US Marshal showing up within 30 minutes. No exaggeration. They once said, "We followed the sound for a mile to find you" I was using it outside, at my high school. Filled my mom's entire VW Squareback! Even had to scoot the driver's seat forward so I could close the back!

I fabricated brackets from duct hanging straps to hang a 120V 5" Boxer fan below the power tubes and transformer of my BF Fender combos. Slips over the lower rear panel, and plugs into the 2 prong convenience outlet. No screws/holes/velcro needed. Great video. Love that 80's style _G_ logo.

Very enjoyable episode. I have a 1982 2204 CSA Half Stack. Bought it off of an older gentleman in Hearst, Ontario. He played it twice ever !

@JamesSteeleProjectVideos 9 месяцев назад

I really enjoyed this video! I have two 1979 100-watt JMPs with the 6550s and it is hands down my favorite. I think I fell in love with these heads in my early 20s when it was the first Marshall I was able to buy (used). Mine are both modded with an effects loop and some preamp tweaks so I’ve probably hurt the collectibility, but so be it. You’ll pry my two JMPs from my cold dead hands! I would love to learn how to bias my amp some day.

Love your vids and playing! Those master vol ones are great too, my fave is a couple years before, a 1987 non madter 50 watt modded with a 2550 mod done horribly by the guy I bought it from, when I got it I almost stripped everything he did and re did the mod, a 1975 50 watt MKII with a early 74 4x12 with all original non reconed greybacks. Old English Mullards make the final tone difference too!

@davejames8872 5 месяцев назад

Reminiscing when I saw this, thanks! I own a 77 2203 100w Master Lead MK2, had it since 1981 and it just keeps rocking. The quad box is gone but I put 2 of its Celestions in a smaller 1/2 quad size wedge for smaller venues. Haven't changed the EL34s for over 20 years but only play one big gig a year now. This video inspires me to give it a present and get it serviced maybe with with new tubes and a clean (I'll keep the old ones though). By the way my front plate has also worn off the labels & pot numbers. I may get a pro (like an engraver) to redo it as well but I think I will keep it to 10! However if 'restoring its aesthetics devalues it, I will keep the worn look. No idea what it's wort these days but I know they are getting rare.

@lynnyates5973 5 месяцев назад

The JMP was my first Marshall ever ..Loved it until it was stolen ..My tubes ran so hot that there were burn indentations in the back plate ..used the box fan blowing right in the back to "fix" the problem..Awesome amp

I noticed the amp was signed by Linda. Many years ago I read an interview with Dave Mustaine and Chris Poland from Megadeth and MegaDave said he would open up Marshalls and look for her name as it was sure to be a screamer.

My favorites are my early 70's Marshall metal panel Superleads. I upgraded some capacitors, wires, added star grounding and post phase inverter master volume to all of them. 100 and 50 watt tone heaven from every one! Most all were bought in the 90's for $500.00 a head!!

@SeanKerns 9 месяцев назад

@phillamoore157 9 месяцев назад

Agreed....that's a masterpiece of an amp you have there. And, the fact that Marshal had virtually ZERO consistency with parts, or quality, back then, makes a good one even more valuable. There are a few on Reverb I'd consider buying but no sound clips. With the prices they're asking, I don't feel comfortable, knowing that. I envy the guys that have one in good condition, though. Every hot-rodded rock-n-roll amp used that tone as its fundamental tone. Very cool video...thanks for sharing!
