Modus Operandi Boost (Jackson Audio Amp Mode)

[spi]

I don’t know why they claim 100K output impedance (not something to boast about, that’s way too high), but this resistor does not determine the output impedance. It is determined by the parallel with the output impedance of the last buffer stage which, being very low, dominates the output impedance.

good point, I should've considered this, was being too simplistic. and you're right: it's a odd spec to claim.

If it's based on a SHO then they have done a good job. I like this boost and really don't like the SHO!
