Yes, more info is needed. Anyway, here are some hints. If you are using 
single coils, like I do, you have got an antenna for electric fields. 
Keep away from monitors, power supplies, computers. Try to play with two 
single coils and to get the sound of just one single coil screw one near 
to the strings and the other away from them. For amp recording forget 
galvanic isolation, use microphones or if possible for the needed sound, 
connect the guitar without an amp to the mixer. You can decouple Ground 
by special capacitors, to be honest, sometimes I just switch ground off 
without using a capacitor. I don't like gates, better reduce the level 
in passages were you don't play the guitar when you do the mixing. I 
don't like to cut away all the noise in those passages, but ... more 
info is needed, e.g. a link to a sample if you can't describe the noise. 
Eliminating noise for passages were you play the guitar IMO is nearly 
impossible without damaging the guitars signal too.
