mixing guitars

hi. I'm the most noobie here.

my problem is, when i track overdrive guitar(s) it always sound fine. but the problem lies when mixing them. it always ends up sounding too bright, not full enough like proper guitar sound. the hi-mids always annoy me.

My band just recorded some songs in the studio, and we have some difficulties with mixing the guitars. The songs where we use acoustic, and clean guitars sounds really good, but the songs with overdrive/ crunch guitars sounds very muddy. This is really quite strange because the guitars sounded really open and raw while we where recording them, but they just sound tame in the mix.
