Let's talk cabinets. When it comes to achieving certain tones, how do you go about figuring out whether you need to use a 1x12, 2x12 or 4x12 cabinet IR? What are each type good for? Also, are certain cab types considered "go tos" for certain sounds? (e.g. if you're going high gain, then you should be using 4x12s). Stuff like that.
