As above, but a little more advice; use a widener on a few things. Example: Send hat, ride and overheads to a stereo AUX track and insert a widener on the AUX(I like Waves Vitamin for this as you can choose to only widen higher frequencies). Or try a widener on a reverb(with the reverb on its own AUX track, insert a widener after the reverb plugin). Remember that wideners work by messing with phasing(which is why its not good to do on a whole mix)
