14 Sep The Sound Of The Schaffer Vega Diversity (Back in Black)

I know… I know! But you knew that I can’t get enough of it. It’s my passion, my torment, my obsession. And the most sold album worldwide, as well.

Well., let me update you a bit about what has been going on behind the curtains recently.

I knew – directly from Mr. Schaffer – that the “Angus Young” era of the Schaffer Vega came with a Receiver AND a specific type of transmitter.

It was the X10 – naturally – but a specific type of X10. It had (has) a black knob instead of the flat screw of the later models. I really wanted THAT X10 (because I knew that that would give me the sound I was looking for).

13 Sep “Back in Black” Tone Attempt (Cetec Vega Diversity)

I am silent, but that doesn’t mean I am not working. Hectically, actually (replica Schaffer, performances, new ideas, etc.).

I have studied more in depth and tried more experiments.

Here’s my latest attempt.

Hoping you’ll enjoy it,

Back in Black Cetec Vega FRONT Boost Latest Attempt


PS It was recorded with the Cetec Vega – not the Schaffer – as both my working units are at the lab!

02 Aug Ken Schaffer To SoloDallas Comic (SVDS)

While the most pleasing email exchange continues on between Mr. Ken Schaffer and myself,

he just wrote me yesterday – I am without Internet connection where I am right now: back from Spain to my seaside house, Telecom has a broken cable there and it’s taking 10 days to repair it – and I found a way to post it for you all today.

It is a 1978 Comic published on Guitar Magazine. An AD, likely.

Besides the fact that is purely lovely, please take a moment to read and discern who were the stars that were using the Schaffer Vega DIversity at the time

(I will list it here for you in case you can’t see it well: The Rolling Stones, Van Halen, Steve Miller, Mahogany Rush, Peter Gabriel, Fleetwood Mac, Black Sabbath, Johnny Guitar Watson, Stephen Stills (Crosby, Stills & Nash), Boston, Earth, Wind & Fire, Bay City Rollers, AC/DC, Chic, America, Bob Sieger, Kiss, Thin Lizzy, The Beach Boys, and lots more: fascinating find, I’d say, don’t you think?).

We love you Mr. Schaffer!

08 Jul While we wait, “Back in Black” Cetec Vega FRONT Boost

Thought I’d “update” audio wise the state of our research, while we (I at least) wait for the SVDS to come to me tonight.

Since it is now known that the SVDS only boosts from the front panel – which is a different circuit – wanted to try it.

Played with the CETEC-Vega R42/T77


Here’s the result.


Back in Black Cetec Vega FRONT Boost


PS: Important note: recorded with an original 1960s Neumann U67. Settings are IDENTICAL (amp and recording) to the recently played YSMANL video:

04 Jul The Schaffer-Vega Diversity System: The Original 1977 Unit (Updated)

Another smaller but important update on the SVDS. I was able to exchange emails again with Mr. Schaffer during my Italian sleep-less night (majorly jet legged here, and so Mr. Schaffer having come back from Russia where he met his long time friend Sting of which he sent me a few pictures) and he confirmed me the following:



From what I remember (I promised: very dodgy) there was no switch per se.. . the XLR is the clean way out… the front panel “monitor” was never meant to be in line… but a lot (most?) guys used the monitor output, I guess sometimes to overdrive the front end of the amp (which the XLR output would not do).


You know –  you can design something with one thing in mind, but once it gets out to the user, it can turn into a whole new ballgame.   Just like writing a song –  once it’s out there, the writer has like nothing to say about it !

01 Jun AC/DC’s “You Shook Me All Night Long” “VEGA” Series

Well my friends, it’s night here and I have prepared all day long for our departure tomorrow to go “back to the States”.

We’ll be in San Diego, CA, for a month. The 4 of us.

Didn’t want to have you hanging for nothing though. So I did this.

Latest effort in replicating “Back in Black” sound. Using a newly acquired Neumann U67 and all the Universal Audio plug-ins you see in the image. Carefully crafted.

Will update this post with more info. For now, you get the video.
