I was just using a compressor in front of my Boogie on a studio session last night. I was running a Fender (US) '57 Strat through an Alesis Nano Compressor, going into a genuine script logo MXR Phase 90, into the front channel of my Mk IIB on the rthym channel, set relatively clean, with a Rocktron Hush C in the FX loop. I was playing playing some mellow funk leads, & the compressor really added some extra "bite" to it, & giving my sound a little extra funk twang. (We were also running an Avalon tube compressor/EQ on the board while tracking it) I've never tried useing it when playing distortion, & when I start playing live again I'd like to get a compressor pedal (I'm thinkng, a Keeley perhaps?)
