Spacedye,
Hello there, just gave your song a listen and I have to say for an instrumental its pretty cool! I like the vibe you got going on it. Heres some things I want to let you know about though:
1. The snare to me seems a tad dry or something, maybe a longer decay on would help it.
2. The clean guitar crackles (clips) on your harder strokes, I think it might be because you recorded it too hot.
3. Thats it, I dug the distorted guitar part.
Cool song and good job.
John
