Website says his name was Ken Schaffer, not Solo Dallas. You sure you're not just spamming the website?
I guess his company's name is Solo Dallas, I didn't know his name was Ken Schaffer. Again, I'm a life long AC/DC fan and am not affiliated with that company in any way. I actually don't even own the pedal yet as the $399 is a little steep for my current budget.
However, whether you believe or don't believe I'm "spamming" you, the fact is that after he built the first one, he actually gave it to Angus Young in person and Angus used it during the recording of Rock or Bust and now during his live performances:http://www.guitarplayer.com/artists/101 ... view/49471
Didn't think that offering insight on the equipment that Angus Young uses in studio on a thread discussing how to achieve Angus' tone was spam, but if it was I apologize.
