nice tight playing!
and a good clean capture.....
i think the bass guitar is mostly right,
maybe ride the volume on it a bit, at the beginning, a little more level.
but the kick drum doesn't come across with enough punch, or snap.
it's hard to judge,
but wherever the low end of the bass is sitting best (between 50hz and 200hz), boost the kick with a sharp Q either just above or below the fundamental of the bass, and add something between 2-3khz for a little snap.
you should lay a vocal across the top of this,
and edit out the solo guitar where it makes sense,
and make this a full blown song.......
it works great as an instrumental,
but it's strong enough to stand as a song, with 'several guitar breaks' in it!!
LOL
