From H9000 Algorithm manual there are 2 algos I spotted claiming Speaker Emulation
Tube power amp/speaker emulation. This little guy can really do the trick of cleaning up harsh fuzz or to feed a P.A. Stereo in, stereo out.
I’m now intrigued to see if it does what it says on the tin cos a while back I was looking into this, checking Vsig modules and reading online material to see if I could build something there.
I’m inclined to think proper speaker emulation would be more than just EQ, probably doing multiband a) eq, b) compression, c) saturation but probably other stuff too
