How come nobody talks about the JVM series?

Typical 5150 improvements? Nothing about those mods improves a 5150, unless you are trying to make it a soft, midrangey , smoothed out turd. They are biased perfect and they sure as hell don’t need a choke or some bullshit like that.


On that note, I absolutely love the JVM, always have. If you take it for what it is, a modern high gain Marshall, it’s great. Great tones can be had with them fairly easily, I never got the hate for them at all honestly.

Do you have any recordings of it? I've literally never heard a good close mic of it
 
I will do a proper video of my JVM410HJS at some point, playing some post-metal. Personally, I think it is one of the best amps you can buy. Mine cost me £750, or £850. One of the two. Can't remember.

I definitely appreciated that it gave me a modern high gain sound that maintained the Marshall-y character, kudos for that, but it sounded way too synthetic, like hearing a recording in person in much the same way I got with most Engl’s. Maybe in a recording context that quality of it wouldn’t be as noticeable, but in person and when AB’ed with other amps it was impossible to ignore and not as enjoyable for that reason

What you don’t know is that Peavey used a big ass resistor where every other sane company uses a choke in order to cut down on costs - not because it actually sounds good. Also I don’t know what transformers you’re ordering but those descriptions are far from what I’d describe a properly built and biased 5150.

I don’t hate the JVM but it’s not my first choice. They can sound good with help.

That JVM recording sounds much thicker in the lows than I'm accustomed to with the JVM...Pushed resonance?

yeah it is quite high. About 1 or 2 o'clock most likely, as that is what I like in the room. You've also got the additional proximity effect of the close mic on the cab.

Won't pretend my video is representative of all of the tones from it, or even the best tones. But I dig the amp a lot. It pairs really well with my Mark V as well, which I was doing this weekend as a stereo rig.

Yeah not terrible at all, but not exactly a "showcase" of what it can do either - i appreciate you sharing

Is that a mic or an IR? it sounds like it's directly facing the cone, which can work for some amps and speakers but in this case maybe makes the amp sound fizzier than it is (or not? I'm actually not sure because I haven't miced one up before)

It sounds very good to my ears in that recording, I'm used to them sounding "thin"

Yeah a mic. 57 on a V30 cab - the Egnater 4x12.

I didn't spend a ton of time on the video tbh, which is why I wanna do a proper video on the amp.

I've never shot it out against a proper JCM800, but the crunch channel can really slay. In person the amp is very aggressive, in a way that my Diezel VH4 isn't.

I don’t have a real one on me at the moment no, my buddy has one though I could probably steal it for a bit.

I'd really like to hear what you can do with it, as we seem to have pretty similar tastes and process as far as micing amps up

I am with GLP on this, but honestly most of the shitty parts on 5150s annoy me because of reliability; not tone. I can work around most of its tonal idiosyncrasies, I can't work around a gray ribbon belt that's on fire

Ha!! I bought a 6505+ and a few hours later a ribbon cable self-deleted on me and I had to take it to my tech that very night! Amp sounds great though!

This is why I rarely boot mine up. Impossible to find a local tech as I want them to replace that ribbon cable before it goes up in smoke on me

This has happened to me with multiple 5150/6505s ive had, and I swore them off for years.

I bought a new 6505 1992 a little bit ago, and it started blowing tubes and fuses and I exchanged it with another since it was under warranty.

No problems with this one.... yet.

Everyone on the forum seems to think they are bulletproof brick shithouses, so apparently I have the worst luck in the universe

That ribbon belt is one of the dumbest "design choices" in the history of guitar amps though

I gigged my 5150 and 5150II for years and outside of a footswitch glitch, caused by a shit soldered BJT, and a bias diode that let go, I never had a problem for countless gigs. The last thing that bugged me most was due to the 7 pin DIN not making good connection to the footswitch which is when I bought my 94 tremoverb.

If you're handy with a soldering iron, it isn't too difficult to hardwire the connections across the two PCB's. If it is the right cable I'm thinking of.

I never had one issue with my ribbon cables but I did flip the cables upside down - from the factory they’re connected with the cables touching the headshell rubbing them raw. I flipped my cables upside down a long time ago and I never experienced a problem.

You're thinking of the right one. I fucking suck with a soldering iron though. I'd burn the board.

I don't think I've ever seen one rub against the chassis, but I've seen a bunch where that gray ribbon cable overheated/deformed/caught on fire 🤷
