IR vs. Mic - Impulse Response vs real cab: Bogner Helios 50 - SM57 - BAE 1073MP - Suhr ML Standard

In this video I'm comparing some IRs of my recording cab (Mojotone 4x12 with 4 8Ohm Celestion Greenbacks) that I recently made with the actual miced signal.

A full IR library of this actual cab mic'ed with SM57, MD421, SEelectronics VR1 ribbon mic and an Austrian Audio OC18 LDC is available at

For capturing the IRs the signal path was:

Sine sweep from DAW - RME Fireface UCX II - Radial Engineering passive reamping box - Seymour Duncan Powerstage 170 - Mojotone 4x12 (G12M) - Shure SM57 - BAE 1073MP (Neve clone) - RME Fireface UCX II - DAW

Recording signal path:

Fender '95 Strat - pedals (see video) - Bogner Helios 50 - - Suhr Reactive Load (line out to DAW, through to cab) - Mojotone 4x12 (G12M) - SM57 - BAE 1073MP - DAW

I used three IRs from the 20 positions I captured:

IR 05: the actual micing position of the SM57 pointing directly at the seam of cap/cone

IR 04: a few millimeters towards the center of the speaker, slightly brighter

IR 06: a few millimeters to the outside, slightly darker/fatter
