Ok, for those of you who both own a JCM900 and know your way around a DAW:


http://www.simulanalog.org/guitarsuite.htm

This has a JCM900 VST in it.

How close do you guys think this is to the real deal?

Yea yea, I know "DIGITAL will NEVER be able to sound like the real tube amp... but let's not go there. I already get that. I'm just asking how close do those who own a real JCM900 actually think this VST is to their real world amp?


TLDR:

If you own a real JCM900, and a DAW; how close is this VST to the real deal?

You'll never get an accurate answer unless you find someone who has owns both and has compared them side by side.

My guess is that it's not.

What, you implying that there's something inherently wrong with a dual reverb or it's sim?

I for one like the vst.

I'm just currious as to how close it is to the real sound. In fact, I find it to be quite nice actually. Both in it's cranked state, and in it's more... sober state.

The JCM900 Dual Reverb is easily the worst of the 900's when it comes to the stock amplifier. The SL-X and MKIII both blow it out of this galaxy. If I were to get one, it would be an SL-X, since it's actually all-tube, but if I had my choice between a MKIII and DR, it would be an easy and instant MKIII.

If you want the details on it, Cathbard could draw you the Schematics of each one while blindfolded with his off hand.

Ah... I never pretend to know everything. I just thought the JCM900 was one of those great marshals, heh... But then I don't know much bout nothin... oh well, so's life eh?


Thanks for the education...

If you want some killer high gain VSTs, check out the TSE plugins, notably the 808 and the X50. I have heard instances where they make tube amps sound ugly.

+1 combined with Catharsis or Sperimental impulses packs (specifically the ENGL IRs), puts alot of professionally recorded tube amps to shame.

Not exactly. It retains the op amp driven master volume controls and op-amp based FX loop. What they did was replace the op-amps and diodes before V1 in the DR with a 12AX7.
That was the main thing that was wrong with the DR though so the SL/X does sound a metric shitload better than a Dual Reverb.

The Mk3 has that shitty diode clipper out of the 2210 (also present in channel 2 of the 4100). If you remove that it's not a bad amp at all.

Ah, I'll give the x50 b3 a try later. My initial runthrough though left me thinking it's cold... with no warmth. But maybe that's just the settings? Or is that particular amp "cold" sounding to begin with (no 2nd order harmonics and "warmth" like you get with some vst's...)

Well, you need a well-received cab impulse to really bring it to life. The X50 is really scooped though, so you have to push the mids and presence to really make it scream.

I use Lepou Lecab and run 2x Catharsis 1_pres_5 in stereo whenever I want to goof around. Sounds killer.

How can we not go there when that is the specific question you are asking?

It sounds like you're saying 'I know it isn't going to be close, but tell me it is so I'll feel better about it.'

Besides, if I were worried about emulating tube amps JCM900s wouldn't make my list.

I can imagine how it would come to pass though. Somebody tries to make a Marshall sim but it comes out all fizzy and lacking in dynamics.
"I know - we'll call it a JCM900 sim!"
"Genius! Give that man a raise."

That makes perfect sense

Also, I wasn't aware of the other SS BS in the 900's, but that stuff is of little concern to me if there is a giant pile of SS crap in my preamp. With anything I'm playing, the Preamp is the thing I'm most concerned about. FX loops I can live without, and I doubt the MV has that huge of an affect, but making most of the preamp gain come from diodes and op-amps is unacceptable. If I wanted that, I would just use pedals into any old power amp. That's more fun anyway.

oi. What I'm saying here is this: I know it isn't going to be 100% authentic to the original sound... but I bet it comes as close as 99.9%... or does it? There is nothing that chips and diodes can do to truly mimic what tubes can do 100%... as there is an amount of ... "natural errors" that occur within tubes. BUT, and that's one huge but here, They have gotten incredibly close sounding with some sims. I'm just curious if it's more around 99.9% accurate, or if it's 50% or less accurate?

And btw, I'm in love with this JCM900 Dual Reverb sound. It's one of the best I've found on the net so far in so many areas. It's nice and "natural" sounding, and dark... dark without going too edgy on the distortion/overdrive either... but as much as I love it, I'm curious if it's true to the original at all, or if this is NOTHING like the original, and better?

The Dual Reverb's gain comes almost entirely from Clipping Diodes and Op-Amps. That amp has more solid state nonsense in it than a Blackstar HT. (Funnily enough, the guys that started Blackstar are the same guys that designed the JCM900).

If you like the JCM900 DR, why not just buy one? It's not like they're expensive, since they're the least sought-after 900

Get it and make a recording with it and post it here. Then we can tell you if it's believable or not. There are plenty of us here that are intimately acquainted with them.

Hey, the B3 version is outdated. You can download the final version (v1.0.1) at tseaudio.com .. there's big improvements in sound and in how the amp is modeled in general (poweramp, cpu performance etc)
