One of the most innovative drum companies of all time would be Tama, the company which practically invented the word heavy duty and the boom stand! And they make great drums to boot! In the past, Tama relied heavily on the SidePull Throw-off. As time passed, the Sidepull began to be dated, looking more like a block of metal stuck to the side of a fine drum.
The SP series Retrokit™ utilizes a Retroplate™ allows the drummer to mount a Trick GS007 throw-off to ANY Tama snare drum which uses the SidePull throw-off with out rollers, thus allowing the drummer to take full advantage of today’s (and tomorrow’s) best throw-off!
