I have the same problem, it sounds ok on my crappy home speakers but as soon as I put listen through my nice headphones it sounds like its recorded in a fucking public lavatory.

Use a BP filter with some slight LFO changing the frequency parameter. This adds life and I think it helps the mix a little bit by the psychoaccoustic benefits of something dynamic.

Lower all faders
Raise the Kick, Snare and Bass to a level about a third of the way up the faders and balance them accordingly
Raise other drum sounds and balance against previous
Raise chords/arps and balance again
Raise Melodic parts going from aux melodies to lead melody and balance again
Review all parts, at this point the kick & snare usually need to come up slightly
Take a break, come back and tweak
Put a reverb on the send set to a room or maybe a hall depending on the sparsity of the track (more dense, smaller space)
Put a send device on each track (I do this in renoise usually but all DAWs have this feature
Send each part in the reverse order to the faders being raised to the reverb so that you can hear the effect and then back the level off from there slightly
Do not send bass or kick to the reverb

Want to make that big "BEWM!!!" sound from the Lion King movie title?  Take a thump sound of any kind and put it through a reverb set on gigantic and filtered so it's only sending 400hz or lower.  My thump of choice is a Roland drum machine sample, but you can really use anything.

Otherwise, when reverb is for sweetening and not for effect, chop its lows and keep it subtle.  You should literally barely hear it.

Was literally asking about this three days ago while doing a demo of a new track

i just cant get behind digital reverb. it always sounds mad corny to me

so you have a 5'x8' steel plate hanging in your room for that sweet plate verb sound?

Do you guys have any good links to websites which explains for beginners that explain a bit what you're all on about?
I'd fail at step 2 because i dont know about setting up a bus lol, but i am interested in making my sounds sound 'better' so any help would be appreciated,

Check out Computer Music or Sound On Sound. Computer Music is more aimed at people with less experience so start with that.

What software are you running on your computer?

What Rainbowdragoneyes suggests is that you put an EQ before the reverb to cut some bass and mid. This is common practice in audio production to avoid muddiness in the mix.
So the signal flow would e something like this:

  Channel_1      Channel_2           --> Reverb_channel
      |              |               |         |
      v              v               |         v
     EQ              EQ              |         EQ
      |              |               |         | 
      v              v               ^         v
    Send------>----Send->-EQ->Reverb-|       Send
      |              |                         |
      v              v                         v
      |              |                         |
      |              |                         |
      |              |                         |
      |              |                         |
      |              |                         |
    Volume        Volume                    Volume
    fader         fader                     fader

      v              v                         v
           -M    A    I    N    M    I    X-

Yeah, my ascii art sux, but I hope you get the picture.
