    You've only 8 tracks, but you're yer average band with drums, bass ,two geetars and a drunken singer....and you want room for other samples,solos n'stuff.

    Here's how to do it best.
    Record your drums as follows:
    1. Kick
    2. Snare
    3. Overhead L
    4. Overhead R
    5 Guitars and bass all onto 1 track as a guide
    6. Vocals as guide

    Then, when it's all done, you can EQ kick and snare and bounce down the 4 drum tracks onto 7 and 8, experimenting until the mix of the drums sounds right.
    You can also put a bit of reverb onto the snare....keep it short, no more than a 1.5 second decay time, with maybe 50 ms of predelay.
    On NO account put reverb onto the kick drum.
    You should then have yer full stereo drum track, so wipe the 4 individual drum tracks, and start overdubbing, bass first, then guitars onto these tracks.
    I've laid it out as above in case it's an 8 track tape machine, as opposed to digital.
    If you tried to bounce the drum tracks onto 5 and 6 you'll get feedback from the record heads...and the kick on track 1 because tracks at the edge sometimes lose high frequencies, and the kick doesn't utilise too many.

    You can record the guitars and bass at the same time if you can do one of these:
    1. Take the bass straight in thru the desk via a DI box.
    2.Have them miked up in different rooms so they don't intrude on the drum sound.
    3. The guitar amps have a headphone or DI output you can take straight to the desk.
    4. You're using PODs or similar to record with.

    If not, the best thing is just to take the guitars and bass into the desk directly, after using whatever distortion pedals you have. It'll sound horrendously fuzzy...the bass won't be quite so bad.....but it'll do to give you a rough guide to get the drums down with.Then you can do the REAL guitars and bass onto their individual channels.
    Remember,though...everyone'll have to use headphones.
    Getting the sound you want will take time and experimentation.
    Multitrack as many guitars as you can for a bigger sound.
    For example...get your first guitarist to play his rhythm track, then put the guitar out of tune and tune it up by ear...NOT by a tuner...the difference in tuning between the first guitar part and the second will make them sound very full. Change the EQ and distortion a bit, then record again on another track. Take the two guitar tracks and bounce them down to one.
    If your second guitarist does the same, you'll end up with a much bigger sound.
