Which of the Marshall amp sims are you guys using to get this amps tone? JMP-1? There used to be a JCM900 amp a long time ago but it's been deleted.

Thanks,

Roger

I would guess probably because it's considered by some to be one of the worst amps Marshalls ever made.

That is not necessarily my assessment...
 
I have an SL-X, and it would be a great addition to the FAS Amp model family. The SL-X is an all tube 900 and can produce a wide range of tonal characteristics due to it's unique dual preamp controls.

Mmmh......The worst marshalls ever made were the first patch of DSL amps in 1997, not tone wise, but build quality wise. The PCB was so badly layouted, that the negative bias voltage got unstable and tubes failed very quickly......

Anyway, the HiGain Dual Reverb Amps from the JCM900-Series have a solidstate clean preamp with a valve state typo circuit (DC coupled cathode follower)....these amps were often called "the worst amps Marshall ever made....."
The single channel JCM900 or the SLX-Amps are great modern marshall amps! :)
 
As far as I remember, the JCM900 didn't live past the Standard/Ultra days. I think Cliff pulled it because it did nothing about 4 other amps didn't already do.

Pick one of the JVM's based off of how much gain you need.
 
Dave Navarro use to use one before switching to a Bogner Ubershall. I know that because I was with my best friend at the time when he bought Dave's old one. We were joking around, saying that it smelled like cigarettes and Carmen Electra.

Anyway, that one was a great amp.

If he modeled a 900, it probably wasn't the SL-X and didnt' include the 2 separate preamp controls. Using these 2 controls together is what gives the SL-X it's unique properties. I don't know if this configuration was ever used on any other all tube Marshall's, but there are none that I am aware of.
 
Going after the Ace Frehley tone. He used to advertise these amps. Did he actually use one? I read that Super leads and Fenders were used in the early days. So I don't know what I hear in my head is. I assumed JCM900 SL-X. It's been described as a "chainsaw" tone. I'm terrible at describing a tone. I'm hearing what I'm after in Cold Gin live.

He advertised the use of those amps for the 1996 reunion tour. Not a good tone.

The Cold Gin live tone is a very dated tone, and Ace stopped sounding like that by 1976 himself.

As I recall, there was a princeton reverb with a load box or a pre-amp out, driving a non-master volume marshall 100 watt amp. So in essence, the princeton was a pseudo - overdrive pedal/pre-eq before the marshall amp. I read this in an Eddie Kramer interview about Alive! where he remarked that the only live instrument or voice on that entire album was Ace's guitar feed.
 
Here's a pretty good representation of what the amp sounds like with no fx (not my video/amp). He also talks about the 2 preamp controls (2 rightmost knobs) and how they interact.

I modded a couple of these amps last year, those with EL34s and some with 5881....I like them! :)

...and there's absolutely nothing wrong with that ! I could provide the cigarette smell myself and if Cliff could include the rest I'd be all over that model despite its chainsaw character...
 
Great playing and nice tone, but there really isn't anything at all unique about that tone, and there are probably 30+ amp models already in the Axe-Fx that can easily cop that tone, as with most things in the Axe, IR choices really makes the biggest difference.
