So, above I have a link with one of my songs which I recorded with a low budget (The Mask) and under than that link there is an song recorded probably with professional equipment (Dagon). I would like to ask: Is there any kind of digital plugin that will help me achieve that same depth the instruments have on the 2nd link? Does it have to do with how many channels I have available or what equipment I use? Can you send me an example of a song that has instruments recorded with no Microphones and has that same studio depth Dagon has?

Thank you.

Try to add a bit of reverb onto the guitar and multitracking also helps.

Hmmm so the guitars on the Dagon song have reverb in them? And by multitracking do you mean Quad-tracking my guitars?

The guitars are already double-tracked

It seems to me , there is no panning on the guitar , all in center. Also the dagon song has 2 guitars , 1 bass , and drums , yours just a single guitar and a midi drum. Try to add randomization onto the drum and pan it.Reverb would help even just a little , stereo reverb would be even better. Good luck !
