Now if only there was a way for the average acoustic guitarist to engage a service or buy a product where they could generate an IR for such a pedal!

You posted elsewhere an IR that Doug captured from ToneDexter. Do you think that low cut was cooked into the IR or implemented as a separate IIR EQ stage?

Given maybe a preference for a minimum phase IR in my usage to date, is a long IR with all the EQ built-in while maybe possible with the Iridium even desirable?

BTW, that used Steiglitz DSP text arrived two days ago and I've got a used copy of "Mastering MATLAB: A Comprehensive Tutorial and Reference 1st Edition"
by Duane C. Hanselman on its way from the UK (well at least it was a UK used book vender on Amazon).
