Im using the Mapex MC910 multi clamp attached to the Roland PDS-10 Octapad Stand. On the Mapex MC910 I attached the Millenium Cymbal Boom Arm DB115 on which one I attached the Millenium Electronic Cymbal MPS-500 12"Crash Pad.
This Mapex clamp is length adjustable with a maximum of 16 centimetres (6.29 inches), feels very safe and strong, I have been using it for a bit more than a month and it does its job.
Dispatched next day, arrived to Saint Petersburg, Russia in around 10 calendar days.
