I did a little experimenting last night on micing a guitar cab. Sorry, no audio clips. I'll try and put together a sample. The cab I was micing was a Marshall 1960A 4x12. It's loaded with Greenbacks across the top and Vintage 30s on the bottom. Similar to the Freedman cabs. Sounds great. So micing it, I wanted to capture both speakers. So I set up the mic about 4' away point directly at the center of the cab. Amp head was a Ceriatone Son of Yeti. Fairly high gain. I tested five mics: Modded SM57 (transformerless), Audix i5, AKG 414XLS, SM7, and a modded MXL R40 ribbon mic with a Lundahl transformer. I was kind of surprised by the results. I thought the R40 sounded the best and was closest to what I was hearing with my ears. It warm but not muddy. Next was the SM7. A little harsh but would cut through the mix really well. The SM57 was solid. I usually hate this mic on guitar but it worked here. The i5 was too bright. Didn't like it in this position. I do like it off axis close to the speaker. Last was the 414. Sounded terrible. Like there was a blanket over the speaker. Thought this one would sound better. I want to go back and do it with adding a full mix in to see how each mic sounds with the rest of the band.
