S.I.R. 100W SuperLead Schematic pt. II

[Staalhoofd]

Hi Tim!

Welcome to the board. Thanks for the reassurance. Now we know that we're on the right track and there's no use waiting for the AFD100.

I made my own take on #36. I love the sound, but I guess my layout is nothing like the original #36/#39. You can find a clip here:

I'd love to hear what you think of it as opposed to the original #39/#36. Thanks.

BTW,

I posted a remark on Marshall's AFD100 site. They deleted my post! Talking about BS.

Great to have you with us Tim. I think it is safe to say that we all appreciate the work you did with 39 as well as your willingness to answer some of the questions surrounding the legendary S.I.R rental. Welcome!

Ragnar, the amp sounds good dude! Nice cut on the neck pickup. Are your values similar to pdburnette's or have you done something different in the tonestack to brighten things up?

The amp is still the same as before, see layout:

I have removed Resonance Mod and moved the PPIMV there and added Zero Loss FX Loop, the 3 in one Cathode Switch and Mid Shift mods are on but I don't recall at which position. I get this sound by having Master Volume at 8-9 and Preamp at 6-8 and thus hitting the PI hard. The speakers are Greenback Celestion 25W from 1971. The Extar Gain Stage gives more gain and tightens up the sound.

Did you wrote under the name "JayPee"?

[Staalhoofd]

Why do you ask?

[Twiller]

Because I then did read your post and must say you were wrong.

[Staalhoofd]

How's that?

IIRC, I said that Frank Levi did the #36 amp and that Slash used it on AFD. He rehearsed with #39. The JCM800 was #34 used on UYI.

If this is not correct, then please tell what is. We've discussed this on the forum extensively and I believe that what I wrote is according to the general consensus here.

Most importantly: how is being wrong ever a good reason to delete a post?

[Twiller]

Like many others you think that a JCM800 is equal to the popular model 2203, but JCM800 is not a model it's just the "family name" for a series of amps. And regarding the fact that since 1981 the 1959 Super Lead was distributed with a plate with the inscription "JCM800 Series" it's not wrong to say he recorded AFD with a JCM800.

To say it was a 2203 like the Marshall guy in the video is indeed wrong.

[Staalhoofd]

Well,

If Paul Marshall himself says it's based on a 2203, then I guess that we can state that's what the company believes.

Also read up a few posts. Tim Caswell himself clearly says that THE amp was a 1959 super lead (from a time that there was no JCM800 'family name' yet).

A cow is an animal but not every animal is a cow.

The 1959 Super Lead was released under the wing of the JCM800 series in the 80's. But, not every 1959 Super Lead is a JCM800. So, I would say that it is wrong to state that.

+1 Twiller needs to get his facts adjusted The only reason Marshall is referring to JCM 800 is because it's the last good amp "model family" they made and therefore good marketing material now.

[Staalhoofd]

It definitely seems like Marshall is trying to rewrite history to benefit their upcoming marketing stunt.

If the amp was a JCM800 (1959 or 2203), then why do Tim Caswell, Glenn Buckley and Frank Levi say otherwise?

It has been said before that the amp was a 70's Super Lead. That already means different PT and OT (which obviously have a HUGE impact on the sound).

Your contribution is much welcomed Tim.

[Kapo_Polenton]

Staalhoofd, your amp has the response/attack nailed in just right! Will be interesting to hear how mine sounds if I can get her up this weekend. Yours has the nasal thing down pat. Isn't the AFD100 site supposed to have some video updates today of Slash playing?

[Kapo_Polenton]

I love this post from the AFD website:

If you haven't done so already, read the 'Story' section on the site here. It will give you an insight into the background of the AFD100 amplifier, first though let's try and clear a few things up: Slash has stated in the past that the amp he used to record Appetite was a 1959T that had been modded by an engineer called Tim Caswell. More recently, it was stated that he used a JCM800 for the recording. Without trying to confuse or start being over technical, this amp should be looked at as a whole new project, and not just a 'reissue'. What we are doing is recreating the TONE of Appetite, in whichever way we can and most importantly, to Slash's exact specifications

So essentially they are saying "forget" about Slash continuing to emphasize that this was a JCM800 and that in fact it shouldn't matter what it was because this is an entirely new amp. Slash has "stated" in the past that it was a 1959.. I guess he just forgot and it doesn't matter, it is just all for fun... Staalhoofd is on a mission though,love the posts on the site.

Reminds me of when Peavey came out with the 5150's.
