Tube Screamer using SCR for clipping

Diyers,
Has anyone tried this?

hmm ... "stump pedals"

Does this mean you have to be an amputee to use this project that Daniel Lamb has been working on "relentlessly" for the last six months?   

My understanding of SCRs is that they provide a way of only allowing some of an AC waveform to pass; ie they pass current until the input reaches a certain voltage and then switch off (abruptly).  I can't think of how this would sound good as a diode clipper.

And the stock TS diode clippers work in an opposite fashion, ie switch on when they reach the Vf of the diode.   

Also don't SCRs only work in high voltage applications? eg light dimmers and variacs?

I search NTE5400 and I thinks it's 2n5060 in a TO-92 package. I got 4 pcs of this

Unfortunately, this procedure fails to effectively capture the tone quality of the individual analog devices
being emulated.
  Anyone who knows the lineage of the TS also knows how unfortunate it is that it fails to capture the tone quality .
  In order to correct the shortcomings found within digital ???preamps, an analog device is
proposed here that allows diversity offunctional controls, as well as excellent tone
quality.
 
  Too bad there isn't a soundclip.
  Nicely prepared page there.
  Not quite sure which has less long-goings, TS's or Digi-Pre's.
