Big George Waters and all, to be clear i should mention i'm responding to an old thread, in case jodeen is still around (i now see they may not be) and because the subject interests me.

I know that Garry Goodman of O4P experiments with more extreme strings than they list on the website, so perhaps that Warr has/had an experimental Ab4 string.
Garry has reached G4 on 34" before now, on a triple-octave triple-course 12 string:

oh yes, I see that.... I'm still learning how things work here !!

That Warr sold, in fact there's all kinds of tapping instruments coming and going real fast on Reverb, one Stick from the 1980s, an Ironwood that was being advertised as a 1990s stick - that sold crazy fast !!

I'm hoping to see an early Grand Stick show up there, I know if I am patient one will and this time I will be ready.

Cheers !!
PS: did you check out that old thread where Greg posted that video with Boris ??
That guy can play !!
