It all boils down to JCM900 SL-X vs. 5150 I/6505

That's got a nice growl to it. I miss having a Marshall around. (And I love the Slaughter Of The Soul bit in the first clip. I used to soundcheck with those riffs all the time at gigs...)

 

[Mr. Brokenamp]

Marshalls from that era are notorious for bad solder joints. Plus SLX models have a load of solid state garbage in them.
On the other hand old 5150 heads are tanks.

Nah, it's the JCM900 Hi Gain Dual Reverb (models 4100, 4101, 4102 and 4500, 4502) that has diode clipping. SL-X (models 2500 and 2100) is the full tube one.

This is correct. The SLX is one channel of tubey goodness, and pretty well regarded. It's the Dual Reverbs that most people dislike.

I don't think it's even the diode gain stage that's the issue with the Dual Reverbs- the JCM 800 2205 and 2210 have clipping diodes, and nobody seems to take issue with those, and the Silver Jubilee has them as well, and a lot of people rank it among Marshall's best sounding amps, and everyone and their mother on here throws a Tubescreamer in front of everything- it's that the Dual Reverbs sound thin (especially compared to the single channel 800s), brittle, and overly bright.

Wow! That sounds pretty fucking rad for a jcm900!! I've only heard that dual reverb bullshit amps that are fucking ear pearcing and overbright :S. That was great! I got myself a jcm800 2204 from 1986 sounds pretty similar to your 900. maybe not that "gnarly".

 

[Mr. Brokenamp]

No they do have solid state tech in them. They have TL072 op amps in them. Good for mic preamps but stupid to put them in guitar amps.

Oh
and at second glance watch the levels on your effects loop or you will destroy the solid state loop really quickly. The transistor right there at the loop is probably a BC184 which off the top of my head is the equivalent to a 2N2222A I think.
But those parts are really common so are all those op amps, same ones used in MCI mixing boards for example.
Personally I wouldn't go near an amp like that, from experience they turn into a headache.

 

[Torniojaws]

Don't worry, I don't use effects I like to keep it simple when it comes to amps.

 

[Mr. Brokenamp]

No problem there then
BTW the clip does sound good.

 

[KeithRT99]

i like the clips, it has a nice mid range snarl to it.

1993 The introduction of the JCM900 SL-X amps. 1990 The introduction of the JCM900 MKIII amps.
Necroticism was recorded and released in 1991

I think they were used on Heartwork, not Necroticism and this thread is nine years old btw.

Who's more foolish, the necrobumper or the fool who follows him?

 

[~BURNY~]

Maybe the fool who follows the fool who follows the necrobumber or maybe not... I have no idea.

Did you read my post or was it TL;TR?

 

[Jormyn]

It was a joke.
