I play drums, percussion, and occasionally acoustic guitar in a band. All the instruments I'm selling have been tested by me, and I can recommend them with confidence. I also have other music-related items for sale. #mondo band related items These are brass bridge pins that sparkle on stage. The sound also became...sparkling, I think lol. The size may not fit your guitar. The diameter of the pin base is approximately 5.0mm. If the hole size is larger than this, it will be loose, so please be careful. I had no problems with my Morris, Ovation, and Aria guitars, but it was loose on my Taylor. I've fixed it by wrapping the pin with electrical tape.
