Some drummers go round in circles,
Gary Husband got a Tama endorsement in the 80's, changed to Yamaha, then Pearl, back to Tama in the early 2000's, tried DW for a while and now it's Pearl again.
Tommy Lee: from Sonor to Pearl to DW to Pearl to DW...
True, though it's rare. And it really depends on the company and how they feel the move
back will be perceived. On one hand, it could suggest that the artist loved the brand so much, they came back. On the other, the number of moves may seem disingenuous, and be viewed by consumers with indifference. For example, if a drummer had been a lifelong Yamaha player, then switched to Gretsch, then back to Yamaha a year later, that tends to look good for the Yamaha brand. But
too many other companies in-between would erode the artist's sincerity (in consumer minds) as a brand ambassador.
Sometimes an artist is
so big or influential, the companies don't really care. Buddy Rich moved around between Ludwig/WFL and Slingerland. Of course there was a well-known war between the heads of those two companies, so whoever has Buddy,
wins. Tommy Lee would be another, Steve Gadd, Bozzio, etc. Then again, older artists aren't known for hopping around (in
any sense of the word!)
Sometimes, a company draws a firm line. Ludwig is one of those with regard to a few folks. Even though the old management is long gone, some things are unofficially written in stone. I can just imagine a new employee being hired: "Welcome to the company! Oh yeah,
no (name) and
no (name)!"
I've never gone
back to a company that I had previously left. Some of my affiliations are lengthy by normal standards - 28 years with Sabian, for example - and I don't envision making any changes. I'm very happy with the products I use, and a company would have to change the quality, or cancel my deal, or go out of business before I would consider leaving. And a few of those have happened, however I have never been dropped from a company.
