Fab piece of kit used with my 1985 Ludwig Rocker kit. This little clamp on tom arm means you can relocate a tom elsewhere on the kit. I put mine next to the floor tom and it looks great. Means you can keep the ride cymbal nice and close. Strong and sturdy, high shine chrome plated. Ball joint means that the angle can be fully adjusted to get the tom in just the right place. Also useful if you wanted to mount a woodblock or cow bell or any other piece of auxiliary percussion on a 9.5mm rod. There is also a memory lock collar which can can be adjusted and secured in order to facilitate quick assembly, all tightened with a standard drum key. In terms of playability this little clamp held my 14" tom fine with no problems after a three set function gig. No slippage at all and both the ball joint and the clamp to the cymbal stand held fast and retained the position they had been locked in. The clamp is small enough to fit to any cymbal stand and can be easily located to facilitate easy playing. All in all I would give this classic piece of Ludwig hardware 10/10. Good price too from Thomann and arrived super fast!
