on all our songs... start with getting as full a drum sound as possible. Get the kick drum and bass drum slotted together on different eq's. Work out the panning of each guitar track and also use small amounts of eq to give them indivual space. Always compress vocals when recording but usually add a compressor in the effects bin as well and add small amounts of other effects i.e reverb/chorus. Get a basic level set for each instrument. Using volume/eq and panning do the best to seperate each instrument, then listen a further 1000 times to make sure it all sounds good.
The track we posted yesertday used this method and took about 2 hours to mix.
The first track we posted called easy feed took no less than about 4 days.... depends how busy the song is and how well recorded it so you dont have to clean to much up.
