Beyond two or 3 mics plus the PZM added in -30dB to -25 dB on a 1 speaker cab and you start to get the audio equivalent of overcooked oatmeal, everything just loses definition and gets sloppy, just like in real life on a small cab.Hi, yeah, these are great. I sat down for another session in CabLab and exported some 2 mic and 3 mic mixes. Really nice range of colors in the pack. Not too many, and definitely not too few. Cap, Cone, Edge per mic is enough for me. Lots of mics x 2 (DI and Power Amp). For 8 bucks... can't beat that with a stick!
What's your opinion on CabLab mixes beyond 3 mics? I think it depends on several factors, but I have heard it said that beyond 3 or 4 mics you start to lose clarity.
Phil Spector was notorious for using 3 mics on one speaker in lieu of using EQ. The differences in frequency response between mics he used as EQ.
If you are really careful with mic positioning on a 3 through 8 speakers in a cab setup, you can use more mics in an IR mix, but it all depends on mix proportions of each mic and listening for that "event horizon" where you start to lose the depth and definition IMHO.
