There's a trance track (called Crazy coming out on mondo soon) which I put a reverb on the bassline that only opens on the high notes using a gate, that sounded wicked.

Don't see why you shouldn't try it, depends if you like your track getting dryer when there's more things in the mix, sometimes reverb stops complex things sounding too cluttered and lets your brain seperate the sounds a bit so you may find that it doesn't really help clean up the mix how you imagined.

But if it works then... !
