  • A Demon Drive problem.

    Hello there, I'm new to this forum, though I frequent another drumming forum on the web as well. I wish this didn't have to be my first post, but alas. As a heads up, I tend to post very long and in complete detail, just a heads up.

    So, I decided to upgrade to a top of the line pedal a while back, and opted for the Demon Drive double kick, being a Pearl fan. Ordered it off of Ebay (Low price, high seller rating), and when it arrived, I set it up to my specifications (Long board, high spring tension, forward beater position, slightly larger beater angle, basically every tweak possible to get more power), and immediately noticed a problem. When I was playing it, there was no issue at all, quite the opposite; played like a dream. However, if I took my foot off and pulled back the beater with my hand then released, just letting it swing, there was this irritating clicking. It's not a huge problem in the scope of things, but it's still a problem, and having paid as much as I did, I wasn't satisfied with that. A local music shop, my engineer dad and I all concluded that the noise was from play in one of the joints in the direct drive link, which is something no adjustment is going to fix. I ended up sending the pedal back (At my expense), and the seller said they couldn't detect a problem with it at all, then sent me a new one. It had the exact same problem. I sent that back, again at my expense, and bought one from the local store. Higher price, but I could at least be sure that they'd be of more help in the matter. As of now, I've spent just under $800 trying to get a not clicking Demon Drive (That number arrived at by adding the price of the one I got from the store and the shipping from Ebay). We set it up to those specifications in store (Short of adjusting the beater stroke, which I did at home), and it seemed great at first. There was some clicking in the left foot pedal, but it was far less substantial then in the replacement one I'd been sent, so I figured I could live with that and took it home. Again, the same problem seems to be showing up, and I have no idea why. Again, I'm quite sure it's a problem with one of the direct drive joints, but I have no idea what's causing it. Here is a video detailing the problem, shown on the second pedal I received from the Ebay seller: http://www.youtube.com/watch?v=gtDpQ...1&feature=plcp

    That said, I absolutely love this pedal, and want to play it for years and years to come. I just want to have one set up so it's not clicking like this, if possible. Thank you for taking the time to read this, and I hope to hear some advice.

    It could be the spring. Put a tiny dab of grease or oil (very tiny!) where the spring hooks on the top and bottom. Get it on/under there good. Also, make sure the spring isn't twisted in any way. Beyond that, why take your foot off the pedal in that way? Yes, the driveshaft will develop play in time and make a noise if you let it thrash itself as you describe. BUT, it would likely only really make one good "Click!" sound. If it clicks repeatedly as long as the beater is moving, it is likely your spring. Mine has also done this. Easy fix/adjustment. Hope this helps. Welcome to the PDF!

      I'm fairly sure it's not the spring, because it's coming from the slave pedal even worse than the main pedal and, of course, the slave doesn't have a spring on it. Did you see the video I linked there, out of curiosity? It was near the end of the wall of text, I believe.

      Thanks for the reply, and thanks for the welcome

        It seems to me that if the only time you're having the problem is when you pull the beater back with your hand, then it's functionally not a problem.

          If its the same issue that I had, apparently the first run of Demon Drives had a particular screw that stuck out a bit too far and rubbed on the slave side beater holder, causing a clicking sound. They recitified this for the subsequent runs by redesigning the screw for extra clearance.
          You can order this newer part through any Pearl dealer for no more than a couple of dollars (my dealer sourced it for free!).
          I believe the product code is 'ME-731U'.

          If you click on the 'Support' tab at the top of this page, go to 'Spare Part Catalogs' and then '2009 Spare Parts Catalog', you can view the part Im talking about.
          Its on Page 2, Box E, Part 1-A.

            Dave777: Strictly speaking, I think you're right. It doesn't really affect playability (Except perhaps on the first pedal, where I could actually feel the click while I was playing). Still, I hadn't expected that on such an expensive pedal, and am perhaps a little bit disappointed.

            idrum2.0: Yep, I saw that problem when I was trying to diagnose my own; that's not it. These are brand new pedals, at earliest from 2011, and I checked that screw on all three models; it's not that, unfortunately. Unfortunately because it would be a simple fix if it were so. Thanks though!

              I know this is an old thread, but I'VE DETECTED THE PROBLEM!!!!!!!!!
              The ME-739NA axle shaft is the culprit. This part is actually 2 pieces - no screws or bolts holding it together, the axle itself and the outer sleeve are held together by pressure. There is a slight amount of play, and that's what causes the clicking.
              I work at a music store, and a customer brought his 2 month old pedal in for repair. I've taken apart and reassembled a great many pedals over the years, so this problem was fairly easy to find.
              This should be cast as ONE piece. (in case anyone at Pearl is reading this)
              I'm contacting my Pearl rep on Monday to get a new part under warranty.

                Hi, I've had the same problem with my DD Chain pedal. The hexagonal axel is defective and the grooved bit that the beater mounts onto is rotating. It's actually so loose I can slide it right out of position.

                The worst part is that the wait for a new axel, according to Pearl, will be 5-6 months. Crazy!
                Wondered if you had the same result?
