your advices to guitar sound

so did I land in the wrong subforum, or is the track to short to say anything?!
Bit of helpless :(
 
It's a little fizzy but not terrible, not something a little EQ cut around 5-7kHz can't fix.
Generally you can add some dimension to guitars by cutting somewhere from 500-800Hz, but that depends on the rest of your mix.
And there seems to be a whole lot of nothing on your file, might want to check that.
