I just received this yesterday and it’s not compatible with the Yamaha cymbal stands I’m using.
This tilter is NOT compatible with the following cymbal stands:
• Yamaha CS-3 (lightweight aluminum version)
• Yamaha CS-650A/655A (straight/boom, single-braced versions)
I believe this tilter extension is for the heavier duty (900 series) Yamaha cymbal stands. I paid $20.31 with tax. The current store and store online price appears to be $22.99 plus tax, (¿shipping?), etc.
