Celestion Vintage 30 - 2002 Mesa Boogie Traditional 4x12 - SM57

I made impulse responses of my Mesa Boogie 4FB Traditional Straight 4x12 cabinet loaded with Celestion Vintage 30 speakers. I used a Shure SM57 on all four speakers and have uploaded on-axis IRs in 0.25inch (~0.6cm) increments from 0.00” to 2.5” from the cap. Off-axis IRs were captured in 0.5” increments. Recommended starting points vary depending on amp: Mesa Rectifier Vintage Mode - 0.50” from cap Mesa Rectifier Modern Mode - 1.25” from cap Peavey 5150/6505 Lead - 1.50” from cap I will be using this cab as a load to train my high gain amps for both Full Rigs and DI captures with the ideal cab load. I also intend to provide a Part 2 to this set, but with non-SM57 microphones. The cabinet has a production date of 2002 with 8 ohm Vintage 30s from 2001. The cabinet is comparable in dimensions vs other 4x12 cabinets. It is not as tall as the Mesa Standard Oversized 4x12, which is well represented on TONE3000. These V30 IRs in general are warmer sounding compared to my IRs of my 16 Ohm V30 in various cabs.
