These items are pulls from a working yamaha cs series synthesizer. I have taken the time to run signals thru each and every one and compare them with respect to frequency characterrifics and can certainly say they are well matched. Because I don't know where these are shipping to I cannot accept returns as different airports run different safety measures and scan items with potentially harmful waves. I do expect to be offering another small quantity in the near future so don't worry if these sell out fast. You're welcome to see my previous and feedbacks on similar items.
