https://www.sabian.com/en/pages/cymbal-refresh I have used this service a couple times now and no issues whatsoever. I recently picked up a Sabian Artisan 20" Light ride used from EBay. The cymbal had no structural issues but it is a tad too washy and dirty. I reached out to Sabian and discussed what I wanted to hear from the cymbal. The Sabian Agent suggested a Sound Control Flange be applied , and I also asked for it to be polished to a brilliant finish as well . The reasoning being that this would tighten up the sound and enhance the stick definition. I should have the cymbal back this week or next. Before Pic. I will post after pics when it gets returned. Note the $40 price includes return shipping !
