05 Mar The “Raiders” strike again! SVDS tone on a Mini Marshall MS-2

And another SVDS test recording. Probably with the smallest possible amp to test with: A one watt battery driven Marshall MS-2: marshall ONE watt mp3

Recorded nonetheless with our usual high standards:

Now, even such a small amp can have a lot of balls when pushed with a SVDS, right? And the replica will do the same great job!

This “test” has been missing for a long time. Too long.

Technical Info



PS The more I think of it, the real thing I was willing to say was “The Touch Of The SVDS” (on any amp it goes into).

I will say it now.

And you folks want to know what the SVDS user manual (and some ads) used to say? “We beat time and space”.

Boy, wasn’t it real for us. These units have beaten to hell Time and Space. Yes, because 30 years later, they’re still here and working, and making their thing. 

Wow. Just wow.


See for yourself!

03 Mar Franz, Fil & The Schaffer-Vega Diversity News

Sounds like the name of a band, really (Huey Lewis & The news, for example) but no, not really.

Listen to (and watch) this, and rejoyce, you people of the Schaffer-Vega Diversity Union!

Some updates and Goodies inside.

Technical note. the Marshall 1959 used here had the following settings:


Presence: 0

Bass: 6

Mids: 4-5

Treble: 6

Volume: 7


That is, typical Angus Young settings.

The attenuator was still used, but less i.e., the amplifier loudness was definitely higher, finally breaking up a bit more the speakers (Speakers used were original 1979 G12-65s).

Microphones used were one vintage Neumann U67 and one vintage Neumann U87. L

A little reverb was added in post, as well as very mild equalization (some very mild mid-scooping on HMF and LMF, nothing else).

The guitar is a 1969 Gibson SG Custom, with a new, Angus Young signature bridge humbucker.


NO whatsoever gate was used. Nothing. What comes through the microphones is what you hear. Basically, no hiss on this unit. 

Out of the three, working SVDS units we have, this is definitely the best sounding one, in terms of almost not audible hiss. Almost not there! What you hear is what it is.

29 Feb The “Mystery” of Angus Young’s Tone in “Let There Be Rock” The Movie

Heh. Dont tell me – well if you’re passionate that is – that this thought /question hasn’t crossed your mind at one time or another?

Well, if it has, here’s some of Franz’s and mine thoughts.

Thanks to the recent “discovery” of an image grabbed, analyzed and posted by member Dries in this post (here) it was a clear fact that the Schaffer-Vega Diversity System (SVDS) was there and it was ON during the concert.

WHY keep it on and right next to the amps if it wasn’t being used? WHY? I would never keep expensive things that I am not needing nearby. Too much confusion, especially at a concert where a movie is being shot with thousands of people.

And WHY is it TURNED ON???

09 Feb Angus Young’s Guitar Style: It’s PHYSICAL

I remember telling myself (and everyone I talk to about this, been years) how I always though Angus’ guitar style was physical.

This struck me as an evident truth when I got better at it. It still strikes me when I have to play lead (try to) like his lead solo on “Rock and Roll Ain’t Noise Pollution” posted the other day. If you look at the beginning of the solo, there is a major (in terms of, intense) bend there, done on the D string. I am sure that that is how he did it on the album. It’s a freaking tough job and it’s completely physical.
