    So I saw a review of the 2555x on YouTube and the reviewed mentioned that the EUROPEAN UNION modern electrical standards wouldn't allow for the exact replica. So Marshall had to design the 2555x to meet this new B.S. but they had to add an emulator to make it sound like the real deal.

    My jaw dropped.

    An emulator on a predominantly passive design. Please do tell?

    Wait let me thinks about this.
    What you are really saying is that the EU forced Marshall to place a Kemper in silver tolex and call it a 2555X.

    I don’t know about any of that but I can say the 2555X is a great sounding amp. You can pull great tones out of it. The fx loop is also very transparent while my 2203x was not.

    Did you ever play one? You’re jaw would likely drop again if you did. The EQ is very sensitive. I got mine for $1629 brand new shipped to my front door when they first came out and I preordered one from MF.

    I see no digital bullshit in mine. Just different boards and assembly, probably for cost effectiveness. Who was this review by? Anyone credible? Or is that just more internet horseshit? I'm going with horseshit. Maybe they had to tweak a few production methods from the original but the 2555x That I have isn't a modeler anymore than any other Marshall reissue.

    This seems absolutely ridiculous, but it would be so funny if it were true.

    If it were wouldn't all reissues have to follow the same standard? Bullshit.

    Dude, anyone with 'processing' knowledge knows what a processor looks like. Modeling amps require this component technology. There are none....

    If there is any changes due to electric safety codes, it's in the power supply, not in signal path. ..bull..

    "Emulation" doesn't have to be digital. Weber makes solid state "Copper Cap" rectifiers that have dropping resistors to emulate the sag created by tube rectifiers. Speaker response can be emulated with a choke, caps, and resistors.

    Without seeing the review in question it's impossible to judge what the reviewer was trying to say. Most likely he meant they had to change some parts of the circuit but did things to try and make it sound as close to the original as possible.

    One could say that Friedmans emulate Marshalls, without meaning that Friedmans are digital modelers.

    Exactly, and I think this is the case. I had both a 96 2555SL and the 2555x. The circuits are undeniably different, especially the power supply sections, so I do believe they took the liberty of applying some "tweaks" here and there to get as close as possible. I wouldn't call it "Modeling", as in the thread title, but I guess some might call it "Emulating".

    It's probably someone not understanding RoHS guidelines. LMAO

    Doesn't the title of the thread say " plus modeling" ? Modeling is digital processor based no?

    The title of the thread says "plus modeling".

    But the first post just said that some youtube reviewer said Marshall had to change the original circuit and add an "emulator" to recreate the original sound.

    People have looked in their amps and affirmed there's no DSP chip.

    So my guess is that the youtube guy may have used some form of the word "emulate" to mean they had to intentionally design in sag or compression or something that the old circuit achieved naturally. And that the OP heard the word "emulate" and thought that meant "digital modeling".

    It would be a lot clearer if we had a link to the youtube review.

    Or, we don't really care that much about rumors and simply play them.

    The reissue sounds awesome. I don't care if there's a case of hot dogs in there.

    Tech21 uses the phrase "analog modeling" to describe their SansAmp designs. No DSP, no analog to digital conversion, just solid state analog circuits designed to emulate tube analog circuits.
