1968 Marshall JMP Plexi Demo

[KfirOchaion]

THE sound that i have in my head. Right there.

[LennoxBrigade]

Thank you Jim Marshall for all you've done. RIP.

Oh my god, the holy grail of tone right there, BEHOLD!

[Stashmanfpv]

These amps (and most clones - Ceriatone comes too mind) are some of the BEST examples of these amp tones available - PERIOD! This is what made the rock n roll greats, after modding the Bassman, of course,
Even my modelers, Fractal, Helix, Kemper, and my new Quad Cortex, deliver these sounds in spades and I always start at the Marshalls and then work my way into the clones such as the Friedman’s etc. which are the “modded” versions of what we all crave...
I had the Friedman Small Box 50 head and cab and it was simply glorious, but the COVID bug hit and forced me to part with it and some things I can never afford again. :-(. Thank goodness for my modelers as I was able to “capture” those tones before letting those amps go and even though they sound spot on, there’s still something about a live rig, pushing air, that nothing can truly duplicate.

Bottom line is, these amps will ALWAYS be classics and the tones we all look for. 🔥🔥🔥

Thanks for the video and the killer tones!
Best! ✌🏼

I have a pair of '69 heads, one with tremolo. I purchased them in '79 for $500 w/ greenback loaded cabs. They have been maintained carefully & still sound enormous. But the volume will neuter you. An OCD in front of them is pure heaven.

Jim Marshall had the shop and a sound he was after listening to what guitar players that came into his shop wanted. But it was Dudley Craven and Ken Bran that worked on the amp Looking at pictures Hendrix, Page and many others didn’t blend the channels. They just plugged into the upper left high treble input.

Marshall JMP? - It's a good place to be!

I'm very happy with my 1987x Plexi... use it with a small Rock Band and playin' in the local Pubs... got the right volume for these gigs.

To clarify matters, a true "plexi" is a JTM45 or JTM50/100 or any early plexiglas panelled Marshall, end of story. When the JMPs switched to metal panels in 1971, they were no longer plexis, and by that time the circuit and sound had changed somewhat as well.

[RockNRoller]

Proving once again that's impossible to play an amp like this without staring at it. I got my first 100w Marshall half stack w/G12H-30s in 1978 and I've practically never looked back. I lost that one in a fire in 1995 but replaced it with many others. Rock on dude!

This amp and an old Fender Deluxe are the Two Essentials of Rock.

When the Marshall sounds like a angry soul screaming, that means it’s working.

[AMPSHOWS]

Great review of a benchmark amp. As you know Jim Marshall did not work on the electric/sonic aspect of any of his amps. He did work on the cabs looks and design.
I interviewed him in 1986 and he explaines this. Cheers!

Thanks for the advice smart man i just bought a blackstar club-20 head with a older marshall 4x10 cab from sam ash in franklin mills in northeast philly awesome sound tight

[carlbrooksjr]

It definitly has that ventsge Marshall sound I always loved the sound I shoot for out of my own Marshall stack I dig it as we old rockers use to say in the old days to quoat one of you earlier commenters and Link from the Mod Squad ...Solid

[TheKassie]

I believe the gainy fuzzy texture has nothing to do with the amp itself but as much as the old cab. Those pre rola drivers add a lot of muffy speaker distortion... if you look at the trainwreck video. It has the same kind of gainy/fuzzy texture. And trainwrecks are supposed to sound a little clearer... another possibility are the preamp tubes.. though NOS but amperex sound very midrangy.

[bughat]

A friend of mine bought the whole stack back in The tubes would run that now.

[AceOfHeart]

Unless I'm missing something I believe the proper jump would be into the low of 1 and into the high of channel 2 and plug into the high of 1.

That's how I do it.

[Atian]

the old plexi is something to hear...:)

2:50 The Sound!!! nothing beats that, Les Paul,

Interesting comment at the end when he said the amplifier "has a nice kind of sag when you hit the notes." I also hear what he is talking about, but confused as to the reason for this "sag". I'm not a Marshall expert, but I think one of the main differences between a JTM and a JMP is the solid state rectifier in the JMP. Since sag is a phenomenon of a vacuum tube I wonder how the JMP achieves this effect? I like this demonstration and sound, though.
