Hi guys, I would like to share something I discovered recording my guitar gear (Peavey 5150 & Marshall 1960av cab). I learned like everybody here, the best way to get a good guitar rhythm tone is get it right from the beginning. So I always spend a lot of time playing with mic position and amp eq. I use a SM57 in the speaker sweet spot to capture the sound. When all is ready to start recording, I always filter low and high frequencies (60-12000 kHz) and add Waves C4, it helps a lot indeed. I know this will be enough for some of you to sound right. Well, I never get good results using only this methods so I always sweep the spectrum to remove unwanted frequencies. One thing I noted is that horrible fizziness in the 1500-2000 kHz range. When I remove 12 db in that frequency (1800 kHz for example using a narrow shelf) I get a clear and pristine guitar sound instantly. That trick will kill fizziness but some richness in the mids zone will be affected too, so set your amp with enough mids before start recording. Maybe most of you already experimented this before. I'm not saying this will work in all scenarios, but in my case it seems the only way to get a clear distorted tone ready to cut thru the mix.
