Psychoacoustically (if that spelt right) speaking, If you roll of the top frequencies of the reverb the sound will appear to be closer than if you left the top-end in. Most good hardware/software reverbs enable you to do this via something like 'high-cut' or 'high-shelf'. If you 'aint got a reverb with this option, feed the reverb to an EQ and roll of the top their. Also, dont forget that a little 'pre-delay' can help, so not to mask the transient of your sound.... eg: the transient (in your case, the drums/percussion) cuts through the mix then the reverb hits the decay and release of your sound pushing it back, so you get an in'your face vibe whilst also adding the harmonics of the reverb to the sound that makes it fatter....and... ,also try gating the sound after the reverb has been added so their is no reverb tail in effect.
