Another great drum tech is Lorne Wheaton, who is currently handling Neil Peart's elaborate equipment.
How about famous drummers who were once drum techs before they made it big... Such as John Tempesta and Charlie Benante.
Yes, there are a few good drum techs here in the Philippines. Though in many cases, roadies or P.A.s are multitaskers. They do not only handle the drummer's equipment; they also take care of the other bandmembers' gear.
One local drum tech that I can think of is sir Toto, who's been long working for Mang Jun Regalado.
