His main preamp was a Mesa Boogie Studio .22, these were run into Crown Power Base 2 power amplifiers. Kurt used these to drive anything from a single stack to four 8x12 stacks (depending on the size of the venue). To get Kurt's tones you're going to at least need a closed back 4x12 cab, anything less and you just won't get the required air movement and low end thump. The preamp was set fairly clean, this allowed Kurt to use his distortion boxes to generate all of his signature aggressive distortion tones.more
