Metropoulos Super-Plex MK II - RELEASED!

It's official! The Metropoulos Super-Plex MK II is here. Redesigned from input jack to speaker jack, this is the ultimate 45/100 experience and beyond.
The MK II features a redesigned boost circuit, new master volume, PLEXI/TWEED switch and more.
Mode 1 is a recreation of my 45/100 from 1966. Mode 2 picks up from there and goes into new sonic territory. The new voicing switch transports you across the Atlantic Ocean with a simple flip.
The first run is 25 amps, about 15 of those are already spoken for. More info at Metropoulos.net

George this is Fil - it sounds sick brother, much love from your old bro!!!

[@bsicabgs]

George is the most brilliant Marshall style amp builder out there without question. Total nerd with this stuff and I mean that as a big compliment😊

[@willdenham]

Agree. I like that he shares his wealth of plexi knowledge with us as well.

[@staalhoofd]

Very impressive. There's always someone on KZbin who says that two amps sound identical even though they never really do. THIS time they actually do! Great job

[@metroampcom]

Thanks! I just dialed them in by ear for this clip. On the bench they get frequency sweeps. The audio analyzer does not lie!

[@pmkrak]

Before anyone asks again. This is completely redesigned amp. This isn't just a few modifications to the original design. It wouldn't be practical to have your original Super Plex updated to this version.

[@willdenham]

Is the JTM 45/100 superior to the 45, considering it's everything the 45 is, just more of it, more headroom, tighter bass, etc.

[@willdenham]

Reminds me so much of Hendix's live sound. Same string seperation/attack, same chime, growl and authority. Just love that burst through it as well.

[@stevencancel1727]

Tweed switch is the winner here, excellent note definition and amazing tone!

[@luka-abodes]

Sounds incredible!!! That is the voice of rock n roll

[@willdenham]

@Metro Amp, Hey George, I was curious, do you ever do your master volume mod on other people's builds? I'm doing a 100 watt plexi build based on the Metro specs given on Valve Storm. I hate MV's normally but am probably going to need one for this beast. Yours is the only one I've heard that sounds good.

[@georgemetropoulos5124]

No time for mods right now, sorry!

[@willdenham]

No problem, glad you're busy.

[@leosun8469]

Awesome, George. Brand new vintage, only better!

[@FuzzFace]

George is a national treasure.

[@Guitar5986]

That sounds glorious! Can't wait to get one to sit side by side with my DVL-1 which is also an amazing amp I might add. Well done George!

[@atbear]

Awesome, George! Here’s to this updated monster being a huge hit!

[@davidreynolds6718]

Sounds great George! I got a DVL-1 a few Months back and it has been fantastic. I love the way it sounds. I look forward to playing every night. If you are considering buying an amp from George, do it. Dude makes great amps that deliver.

[@ericmacewen5583]

Sounds awesome! Killer neck bend at the end too! I heard some Kossoff riffs in there to boot.

[@krausewitz6786]

I'm just gonna say it....I think the Super Plex sounds better than the JTM45/100. It has a tiny bit more sparkle on top that is just lovely.

[@some_g333]

A bit tighter in the low end as well

[@kxmrock]

Your The Man George, No One Gets it Exact Like You

[@fuzzingaround]

George very cool, it's JF one of your first customer back in 2004, I think I both the very first 100W kit of your anyway I have a suggestion for you, try to use KT88 BIAS them like KT66 of course of the power supply will blow unless you modify it and une 100OHMS screens resistor, you want headroom you will, the amp just sings for ever.....that trick comes from Cerrem!! I did this actually on a 50w el34 plexiglass type head.....and it worked...just the opposite of what a normal 50w plexiglass would do (compression wise)..cheers

[@mattgordon5228]

Holy shit that sounds fantastic.

[@curtisrichards1903]

Did you fix the tone stack issue cutting the level off when trying to bring down the bass to get it under control that was in the MKI?

[@bmf5150]

Sounds great george !!

[@jefflebowski1838]

omg…I hear Kossoff, Angus, Lynyrd…unbelievable amp

[@RickyDoverJr]

Sounding better and better George!🤘🤘

[@jefrolawson]

Sounds amazing 🔥🔥🔥

[@willdenham]

George is the spiritual wing of Marshall amplification.

[@OperationEndGame]

Growly. I love it.

[@stickeylashes3416]

That is a beautiful thing.

[@mohany134]

As always top notch talent and attention to details like no other, I tried to email you via the website regarding amp but got nothing so far

[@satch4u3]

Sounds killer!

[@RocketinExile]

outstanding amp

[@OnTheFritz602]

Sounds amazing George, fantastic job! Still using the Next Gen Sozo signal caps?

[@metroampcom]

Actually no, it's mostly Wimas these days.

[@mrcali68]

The amp tones on this clip are so crunchy I have crumbs on my desk!

[@fallingmanjutsu]

Oh yea!!!

[@ckarwosk]

YAY!

[@zenlandzipline]

George, can you turn my Synergy Metroplex module into a Superplex? I want that cleaner high headroom JTM sound

[@mtbmadman011]

Drool!!!!

[@josephculver7341]

45/100 have a replaced OT? Love the videos

[@apeeg86]

That sounds incredible! Is there a bypass on the master volume, to take it to a NMV setup?

[@SonicProvocateur]

Killer sounding amp George!! You know someone was gonna ask: what pickups you got loaded up that bad boy? Cheers!

[@metroampcom]

Of course! Throbak Mick Taylor set

[@peterschaefer1665]

Wow!

[@fearnpol4938]

Did you change the original grounding scheme as it sounds very quiet?

[@metroampcom]

I have an optimized ground scheme in my designs.

[@Murphy_R9]

That is one sweet 59' LP? Is that a RI or a clone?

[@atbear]

Looks like his Gil Yaron.

[@metroampcom]

@@atbear That's correct.

[@Murphy_R9]

@@atbear That is sweet! does Gil Yaron still make them?

[@atbear]

@@Murphy_R9 I think he makes his own version of a '59 LP called the "Bone" now.

[@dBoogieNights]

wonderful. respect to you from russia

[@Foot-N-Mouth]

The Marshall always sounds tighter. Probably because it focuses on a specific range in the mid freqs. All the clones I hear are not as focused and just don't sound as good to me.

[@lousekoya1803]

I don't know what to say !

[@mca1960]

And another copy of a copy, of a copy of a copy, and so on, and so on, and so on. A very boring theme.

[@bluesky6361]

@M C A Do I detect a bit of jealousy there. No. Scratch that. LOT of jealousy with some envy thrown in.

[@ludvanlazarz]

There are not very many circuits in amp designs really. All are inspired by or copies of each other. Same goes for cabs and speakers. You have tweed, blackface, silverface, vox, marshall. Mesa boogies are essentially high gain modded blackface. Dumbles are hot rodded and tweaked fenders. Morgan and Matchless are vox. Etc.

[@robertritchie2860]

Somehow yes a copy. I don't have a JTM45/100. I once had 1973 Superbass 100W head. I couldn't care for it and I was scared that it would fail. I sold it. I have a Gibson R8 VOS LP, its a copy as well. I can't buy an original one. So what to do? Be miserable and not experience very good approxiamations of the originals or go and buy very good "copies" with improvements... Thx for the "copies" 👍😄 Amazing amp by the way!

[@mca1960]

@@robertritchie2860 All good thing on the planet are at least copies of somewhat, isn't it ? A good example is the Concorde and the Tupolev 144, the supersonic planes. So the JTM 45 circuit is a copy of the Bassman. A bit differnt in layout, and that's it. So why no copies on an old Marshall in new direction of thinking ? 😁Every guitarplayer has to decide: is it boring, or is it exciting to me ?

[@doctordox6278]

Mostly it’s about what you do with it
