OK, so does anyone use condensors on their amps? Just curious as I did get some nice strat recordings with the AKG 3000B I bought years back, it was good for chorus fx. 
yesh, I have used several condensers on amps, the best results so far have been a single rode NT5 (basically a cheaper version of the Neumann 184 mic) which I may never afford lol. It's a small diaphram mic, and it's extremley sensitive dynamically, I actually prefer it to the Neumann version! in tone quality. A matched pair will only cost you around £200!
Tried many others, my favourite is still the trusty shure SM57, even over the beta version (they're not neccessarily better). for micing guitar amps. In fact I've used the SM57 on vocals, percussion, acoustic guitars, snare drums, and it's a great all rounder. It's awsome when you have 2 SM57s miced up to a 2x12 or 4x12, in sterio. My favourite sound is with a 1x12 cab, miced up on the front and open back inside, both with 57s. It's a HUGE tone, try it!
