LP makes a variety of models, but Neil Peart's main cowbells are the Salsa Ridge Riders. His set includes a 4", 5", 6", 7" and 8" cowbell.
Custom Pearl mounting bracket
Peart uses custom-made mounting brackets that connect to his rack's tom-tom stands to hold the cowbells in place.
Custom Pearl chain tensioners
Peart also uses custom-made chain tensioners that allow him to adjust the tension on the cowbells to get the desired sound.
