I would definitely say an AEA r92
, an 1176
and a Chandler TG Channel. I personally like the sound a Burl B1 for heavy guitars, but have also had great luck with a Vintech 1272j as a preamp as well. Sennheiser 421
as well if it hasn't been mentioned.
47fet type(AT4047, possibly even a Bock195) for clean guitars. I personally have an Advanced Audio cm48fet that I use for this purpose, but the r92 also does really well a few inches back. I'm one of those that doesn't really like the sound of many mics to close to the speaker. I tend to start my mic placement the distance of my Countryman DI away from the speaker cloth. I find this helps the sound develop better, especially the upper frequencies that can get strident on guitars.
