Schaffer-Vega Diversity System

30 Aug “Tower Power”

In 1976, Ken Schaffer (an American inventor) partnered with Vega Corporation (California) to deliver the best wireless system ever made for guitars – soon spreading to other instruments (bass, acoustic stringed instruments, vocals, etc.).

Schaffer wanted to create the most transparent sounding device but luckily, he failed (according to his own memoirs). This wireless system had a sound of its own and musicians of the time quickly realized it, putting it to good use (Kiss, AC/DC, Van Halen, Pink Floyd’s David Gilmour, … ). Over 1000 Superbands and individual artists joined as Schaffer-Vega clients between 1976 and 1981, some of them using this particular system for over 10 years straight (live and in the studio) even after the introduction of newer and, theoretically, more efficient technology in the 1980s.

After years of research, once we at SoloDallas’ realized the breadth of the original SVDS use in those times, we have wanted the whole world to have that sound, and this time, in affordable packages. The Schaffer Replica line of products was born (2013). (more…)

09 Sep “Nothing is new…”

“… except what has been forgotten.”

Says he. And in fact, the core running underneath is always the good ole SoloDallas team. Same guys as always, but better (only Franz – former product manager – took a long pause, after being the real engine responsible for production and everything else, when we were back in Europe; seems like 100 years ago, now).
In these two+ years here in the US I (we) have worked so hard that I can hardly believe it. I forget how many hours a-day; every day, on Saturdays, Sundays included, non-stop. Hectically. Then I’d take off for a while – but could never not-think about SoloDallas stuff. Just got to do it.

20 Jan Getting that Classic Sound Back

The San Diego Union Tribune

Like many rock fans and aspiring guitarists around the world, Fil Olivieri had a musical epiphany the first time he heard the Australian band AC/DC’s classic 1980 album, “Back in Black.”

That epiphany turned into a decades-long quest for the Dallas-born, Rome-raised Olivieri, whose company, SoloDallas, will be an exhibitor at this week’s NAMM Show in Anaheim. For years, he sought to replicate the striking “Back in Black” guitar tones of AC/DC’s Angus Young, but didn’t know how.

“I became obsessed with it,” said Olivieri, 47, who now lives in La Jolla and was not yet a teenager when he became an AC/DC fan in 1978.

He bought the same guitars as Young (vintage Gibson SGs) and amplifiers (Marshalls). Still, the sound he wanted proved elusive.

Olivieri did not discover until reading an interview in 2012 that Young’s guitar sound owed much to a Schaffer-Vega wireless system. The same system had also been used by Eddie Van Halen, Peter Frampton and other six-string legends.

The long discontinued system, of which only 1,000 had been made, enabled guitarists to roam concert stages at will, without having their instruments plugged into amplifiers. The system included two controls that Young specifically credited for creating the over-driven guitar sound that is a trademark of AC/DC’s “Back in Black.”

After learning that Ken Schaffer had stopped making his wireless system in 1982, Oliveiri tracked him down in New York. They spoke several times at length.

Impressed by Olivieri’s enthusiasm, Schaffer gave the Italian-American his last two wireless units — and his blessing to create the Schaffer Replica, which Olivieri began marketing last year.

His company, SoloDallas, will display Olivieri’s Schaffer Replica wireless unit ($1,299 each) and foot-controlled stomp-box version ($399) at the NAMM show. That fact that AC/DC’s Young now uses Olivieri’s high-end product is an added bonus.

“Muse guitarist Matt Bellamy and Billy Idol’s guitarist, Steve Stevens, both have one now, and Lenny Kravitz, Keith Urban and other guitarists know about us because of AC/DC,” Olivieri’s said. “We made 850 units last year, and Angus has the first one. My company expects this NAMM Show to be really successful for us.”

Angus Schaffer Replica (Guitar Player)

14 Sep The Schaffer Replica at Guitar Player!

Dear Members,

Of course the TSR has been something of a secret… You know, labor of love here on SD. But a lot of things are converging… Our first production run – sold out on the GT and on the pedal – the great unsolicited comments our first users have begun posting here… Then, Fil’s trip to Vancouver to meet with Angus, and the new album – possibly before the end of the year, to celebrate AC/DC’s 4 decades!!

And now the TSR, that started as a “little special something” for our SoloDallas members… is breaking out: we just got the news that “Guitar Player” Magazine has just today published a sneak preview, “The “Secret” of Angus Young’s Classic AC/DC Guitar Sound?” about the TSR. (If you remember, it was a February 1984 “Guitar Player” interview with Angus Young, when asked “Do you use any effects,” he said “I only use a Schaffer-Vega wireless” which brought Fil on the right track on his search for the “Back in Black” tone.)

26 May Less Is More: Mr. Marshall Switzerland Bruno Eicher talks about his TSR Gold Tag

Dear Members,

please say hello to Mr. Bruno Eicher, better known as “Mr. Marshall Switzerland”. I think this is quite the right name for him.

Bruno Eicher receiving his Gold Tag

Bruno Eicher right after receiving his Gold Tag

Bruno Eicher receiving his Gold Tag

Gold Tags and vintage SG’s fit great together, no?














And of course he tried it out right after site member Daniel Meier (who obtained this unit for Bruno) handed over his unit. And as it seems, it sounds great on Orange amps as well:

As usual, I’ll hand over the mike to Bruno himself now:

Wow Wow Wow Yes, thats it! I’m speechless and totally happy with my TSR.

I thank God, Filippo Olivieri and the whole SoloDallas Team for their work and what they created. It took me the last 20 years to find the perfect sound for my projects. With the TSR and my Marshall Equipment, I finally found my personal Bruno Eicher sound.

In the past 20 years I tried lots of Effect/Boost devices, but the TSR Gold Tag beats them all and will always be my number one.

Conclusion No. 1 after the tests: less is more and and without any knick-knacks between (the GT) into the amp!

The TSR brings that honest earthy Rock’n Roll sound to my Marshall Equipment and my SGs.

With the right settings, it’s a breeze to play the right sound from clean to crunch just with the volume tuner on the guitar. And it’s amazing how clean the the single notes and chords are hearable.

Said it and picked up his guitar again (Facebook login required to watch video).

Bruno and his Marshalls. Actually, just a few of them.

This is how Marshall/Gibson addiction looks like in Switzerland. Bruno Eicher is mesmerized of the JMP100s from 1968 and 1972 and collected a few of them.

Bruno's SG's

Just a few of Bruno’s SG’s. Looks like a preference for a specific model?


I can only imagine how this wall of Marshalls would sound. Gives me goosebumps.

Final words from Bruno himself:

As an old, but still young in mind Rocker, I will start through again like in younger years and inspire all the humans out there! Maybe I’ll find on this way the missing band members who will part my passion with me.
I’m searching for: Singer (Bon Scott), Bassist, Rhythm guitarist, drummer!

So, if you wanna join Bruno and rock your ass off: hit it!


Bruno Salute

Final Salute from Bruno


Well, and if you ask me: Could I please be like him when I’m older?

10 Jan First thoughts and impressions on my TSR GT #018 ( Update with advice and a Strat + 1st audio file )


Hello fellow SD members !

I am the lucky first who got to play his unit on this day, 10th of January 2014. I didn’t sleep much to be honest… Excitement all over my body; woke up at 7:30 ready to receive it 😆 . It arrived precisely at 10:39 am ( I’ve never opened a front door so quickly ), but I couldn’t play it until 11:45 ( had to help a friend of mine with university stuff, if you wonder,a girl… yeah girls right ? 😆 )

Franz kindly asked me if I was willing to make a review of my TSR, and the least I could say was ” Yes, of course “. After all Franz has done for us lately regarding the TSR project I had to say yes, and it’s an honor for me to do this 🙂 ! (more…)

05 Jan AC/DC’s “For Those About To Rock (Album Compilation of Covers)”, The Schaffer Replica™ Series (SoloDallas covers)

I am going to try and compile here – this time – the covers that refer to For Those About To Rock.

Just for ease of access really, and to try and keep what I write in a sole place so that you don’t have to go picking up stuff around in bits and pieces.

NOT that I think what I have to say is SO important after all. So the big chunk I am going to say it right after the first three covers. Enjoy.

03 Jan Preparing delivery of the first 25 Schaffer Replica units

Dear Members,

Franz picked up the first 25 built units from the shop today. Now we’ll prepare the delivery. Means: getting packaing material, price quotes for delivery to different countries, writing and printing invoices, attaching the “Gold Tag” brass plates, shooting a photo of each single unit for each buyer, doing a short sound test (functional tests and burn in has been already done at the shop) and writing the delivery notification emails. They will be sent out at about tomorrow, Saturday, 4th January, somewhen in the afternoon/evening.

To mention the procedure again: Every buyer will get a “ready for delivery” notification email with a photo of his unit and we’ll ask for the final part of the payment. After the final payment came in, we’ll immediately send the unit. Insured to the full amount and with tracking. Tracking number will be sent via mail, of course.

And as usual, I’ll end the post with a few photos. The unit you see there, is #001, brass plate not yet attached. Higher quality photos will follow later. Enjoy!
