| Neat clip. Not sure exactly what sound you're aiming for in the end, but off the top of my head I'd say:
1. I wouldn't mic if I could help it. I go direct, but not direct from my bass; direct from my pedal board where I add not only effects but a bit of dirt and even some amp/cab modeling via my SansAmp BDDI. If you go direct from your bass, might want to add some of that kind of stuff at the mixing desk lest things sound weak or sterile.
2. You'll probably want to use a compressor to even out the quiet and loud notes/techniques in this piece. Compression is a fundamental aspect of how most bass tracks are recorded these days. Probably even in a tapping solo piece such as this one.
3. You're getting a pretty decent tone, but I'd like to hear a bit more bottom end. Just a bit. Warm it up a little.
I have no idea how to make things "3D" or "atmospheric." Perhaps someone else has ideas on that... A bit of chorus? No clue. |
