Wow, thanks a lot for the comments guys!
I love instrumentals and it seems as if it is impossible to find any getting airplay any more.
I'm trying to stick to my guns - I constantly get comments like "How come there aren't any vocals" or "this would sound good if you added vocals".
I'm gonna go out on a limb and say there was something going on in the bass besides just acoustic bass. Did you double it with a synth bass in spots? It was thick as hell, not really muddy, just T-H-I-C-K - not in a bad way.
This is just the Trilian Acoustic bass - nothing else - honest ;-)
I don't work for, or get paid by Spectrasonics, but IMHO this acoustic bass is the best!
https://www.spectrasonics.net/products/trilian.php I just mixed it with the drums (and you're right, it's "full") - then tried to keep the guitar parts out of the way ;-)
Thanks again to everyone for taking the time to listen.
