Jimmy started using Zildjian Cymbals upon his return to the Smashing Pumpkins in 1999. Here are some of the ones he's used:

• 14" K/Z Dynobeat 14" hi-hats, Z top, K bottom
• 17" A Custom crash
• 20" Oriental China Trash
• 6" A Splash
• 18" A Custom crash
• 10" A splash
• 19" A Custom crash
• 22" A Custom ride
• 22" A Custom swish
• 20" A Sizzle ride
• 20" A Custom China

Reportedly, a majority of the Zildjians that Jimmy is using are "Z Custom" models which are specifically designed for live performance (see the high hats and ride cymbal in the "Everlasting Gaze" video).

On Zeitgeist, he switched his crash out for a 22-inch Zildjian Constantinople, his new favorite.
