Lately I have been on this kick to make cymbals sound more electronic and 'industrial' for lack of a better word.

I've been taking small lengths of various sizes of chains, from serious heavy chain (with only three links on a ride cymbal they are so big)
down to the kinds of chain that you use on light bulbs.

Additionally, I have been on a magnet kick as well.

I recently took two identical cheap Zildjian stamped ride cymbals and put them on top of each other with three really tiny magnets separating them right at the edge of the cymbals so that a very small gap is made. This provides a very interesting sizzle sound.

and, apropos of the original thread, try this if you haven't already.................
hit a heavy ride cymbal with a stick or mallet and the take your hand and pat the cymbal lightly so that your palm is parallel to the surface of the either the edge of the cymbal or the bell. You will create a beautiful comb filtering effect.

This is a really nice way to end a quiet song.........................hit the last note on the edge of your ride cymbal and the
use this technique to 'wah-wah' the sound as it dies out.

You can also lean over and make 'wah-wah' sounds silently with your mouth right over the surface of the cymbal to create a
comb filter effect. This is a very subtle effect so it's good to mic it well.

I have a very heavy Sabian 13" Bell that I use with a mallet in my right hand and the phasing technique with my bare left hand.
You just altrenate strokes mallet/hand/mallet/hand and it sounds exceedingly electronic, especially if you fade the sounds out so that it sounds like you are putting echo on the cymbal.

cheers.
