Used RotoTom by REMO. I believe it's a 6-inch model (approximately 15cm in diameter). I think it's been about 20 years since I got it. There are no major noticeable scratches, but there are some marks from being hit, and some wear and tear from moving and aging. I bought it new and took good care of it, so I think it's relatively clean. I believe the adapter is Pearl. I've had it wrapped in plastic wrap for over 10 years (see photo 8). I bought it because I was somehow drawn to RotoToms, but I only used it 3 or 4 times because I found it a hassle to bring it to the studio and set it up. As you can see from the condition of the head, it hasn't been hit much. I will remove the center screw (rod: fixing device) before shipping. Please understand. ----------------------- My explanation is poor, and I apologize if I'm mistaken ↓ Please screw the screw straight into the first hole (so as not to strip it). You can install it without tools. (Gloves are recommended to prevent rust) As you screw it in, it will feel like you're pressing on the frame on the head side, and it will become tighter. After that, you can tune the head by attaching the Pearl adapter and then rotating the screw as an axis. *I think it's common to tune it after fixing it to a stand, etc. The Pearl fixing device has a square base on the screw, so insert it into that part and tighten it with the black lever. Because the gap between the black lever and the Pearl fixing device is narrow, narrow the black lever to the width of the fixing device as much as possible before tightening. You may be able to tighten it more easily by inserting a washer (or collar), etc. ----------------------- No claims, no returns.
