Anybody knows what tubes Tommi Iommi used on Eternal Idol and Sabbath reunion? or anything that doest that "trick"? Thanks.
 
Re: Iommi's Tubes

I don't know (nor particularly care) what tubes he or any other rock star uses but IME JJ EL34Ls are very good for that sort of very present tone.

Thank you for your wonderful insight, and unmistakebly original sense of humor.

I kinda care what greats are using, its like if you paint and don't care what Dali used you sort of limit your knowledge ... I believe ...
 
Re: Iommi's Tubes

As far as I know, Iommi has almost exclusively used Laneys. And their EL34's I believe. Also, his sig has EL34's, and ECC83's.

I understand your point but
  1. There are sooo many aspects to the signal chain that have a bigger impact than tubes. For example, Iommi's treble boost pedal back in the day likely had a greater impact on his timbre than his pickups, cables, or tubes.
  2. A lot of one's distinctive timbre comes from picking mechanics and left hand technique that even with a cloned rig you'll only get so close. Given the variation in individual technique, chances are that you'd get closer to your benchmark tone with a degree of deviation from the rig one's role model used.
I think it's more important to know how a piece of kit affects my tone than memorizing my role models' signal chains.

At least that's my opinion. YMMV.
 
Re: Iommi's Tubes

aleclee,
My amp actually extremely preamp responsive, because it is a cascading preamp. So in my case tubes play a role, huge one.
 
Re: Iommi's Tubes

Any tube amp with a distortion channel has a cascading preamp. (ie. all modern tube amps with more than one channel)
 
Re: Iommi's Tubes

Currently, I believe his preamp is loaded with JJs. Back then, who knows.....probably whatever he could find.

Also, around the time of Eternal Idol I'm pretty sure he was using a Boogie MkIII Coliseum head.

100% right. I've accidentally nailed tones with various equipment- a Jackson RR-1 with Duncan JB/Jazz pickups through a Marshall Valvestate VH100 will nail Metallica's Master of Puppets. My Ibanez with JB/Jazz through a tubescreamer into a JCM800 and BBE Sonic Maximizer nails Megadeth. Any guitar through a Boss metalzone gets you Pantera. My Les paul with EMG 81/85 through Marshall JCM800 does not get me near to Zakk Wylde, and my my Axis through JCM800 nails Guns and Rose Appetite for Destruction tone..... all of this I got accidentally.

That being said, I think all that matters is that you have functioning tubes in an amp that's biased properly. Whether it's JJ, EH, or Groove tubes matters little- my JCM2000 401 sounded best with the stock Marshall tubes. As far as whether it's an EL84, EL34, 5881 or 6L6 based amp has more to to with the style of amp- EL84's get you closer to a spongy Vox tone, EL34 get you a classic British Stack tome such as Marshall, Laney, 6L6 gets you into the American Fender/Mesa Boogie category, and 5881 I have ni clue except Marshall used them when EL34's weren't widely available.



As I said before, it's good to start with glass tubes.:blackeye:
 
Re: Iommi's Tubes

Well, I have been reading several boards on Laneys and one thing that people commonly say is that AORs are extremely pre-amp tube sensitive, so ....

I don't think you'll nail those tones with an AOR as the AOR is the early Sabbath sorta sound. The late 80s/early 90s Sabbath is Mesa (Seventh Star or Eternal Idol until Dehumanizer), and the modern Sabbath sound is the GH100TI.
 
Re: Iommi's Tubes

I actually was not interested in "nailing" his tone, I really like his punch and sizzle
of his rythm playing(I know a lot of it is his metal things on his fingers) but never the less I believe its worth a try.

Hmmm. I don't like to play the gear name dropping card but...
As someone who's tried everything from $9 generic chinese 12AX7s to NOS Mullard and Telefunkens in my amps' preamp sections and phase inverters...

As someone who's done power tube swaps in amps he's owned by Two Rock, Rivera, Soldano, Peters...

As someone who biases his own amps by listening rather than simply picking a number on a multimeter...
...I think I'm reasonably qualified to claim some degree of knowledge about the impact of tubes on an amp's tone. If your statement about your amp is based on hard-earned wisdom acquired on a message board, consider me less than impressed. :(

I'll tell you that when I listen to my Paranoid CD, I hear Iommi's treble boost (Dallas Rangemaster?) dominate the tone to the point where duplicating his tube choices doesn't matter. The germanium transistors in the treble boost make a much bigger impact on his tube than any choice of preamp tube.
 
Re: Iommi's Tubes

Uhm .... what does my post have to do with Paranoid ??? Eternal Idol and Reunion stuff around 2000 live(Ozzfest) as well as the album, that's what I was asking about. While I am not a particularly savvy gear guy I did exchange emails with the guy from Eurotube and I believe he was not born yesterday, as well, guys on Racer X's board, who are pretty much a Laney club, have inidicated that Laney AORs are more pre-amp tube responsive than usual, same on Plexipalace. But I am sure you are not impressed with anybody of these people, anyway because none of them:

done power tube swaps in amps he's owned by Two Rock, Rivera, Soldano, Peters...
 
Re: Iommi's Tubes

His tone on Eternal Idol, TYR and Dehumanizer is *miles* away from his early buzzy tone on Paranoid (for the better, I think). Most likely Laneys...with whatever tubes were given to him, I am guessing.

A little harsh there aleclee? Don't toot your own horn there so much. He asked a question, if you don't know the answer, why bother posting?


Although I do agree with Aleclee about the Rangemaster thing, I agree that he's being a little harsh about it.

That said, I don't think a tube swap will make your AOR sound like a MkIII or GH100TI......kinda like sticking EL34s in my Mesa won't make it sound like a Marshall.
