I didn't find any hollow quality about your little snippet? It seems to be perfectly lovely electronic music track? Problems with your bass drum sound may be due to the fact that it is not a sample but an electronically generated bass drumlike thing? The fundamental is pure and low, a little too pure can get it a little lost. Maybe a little grunge thrown in will make the bass drum sound a little more punchy? Otherwise I find your little snippet a lovely innocuous and rather benign groove.

well there are times you can agree too much with remy.... but this aint one of them... i thought it was pretty well balanced... sure we could quibble about it but thats the good part... you've obviously made it to the point where personal finesse' is involved... dont want to asssume to much here but are you familliar with the idea of subtractive EQ?? most of us seem to find that when something doesn't come through for our ear it's often a matter of finding whats in the way.... for instance since say a keyboard and a guitar part could be in the same range and consequently fighting for the same spacein the mix removing a little from either might help to solidify each other... or perhaps removing some of the low end of a guitar part can help bring the bass alittle forward... make sense??? good luck ... welcome to the club...
