DM10 Bass Drum Piezo Fix

(1/3) > >>

Tacobot:
Hi everyone,

I've been a bit of a lurker on here, and used Hellfire's mesh head conversion method for my DM10 set.  It worked beautifully, and I've been playing on that for a good while now.

Now though, I have run into a problem - my bass drum has died on me.  In searching around on the forum, this appears to not be an uncommon problem, and these things apparently break fairly frequently, so it seems like buying a new one is not a very smart option, and I should just go for the fix.  I took it apart to see what the problem was - the sub-resonator plate (the plastic thing) became totally unattached from the metal plate.  However, even trying to re-attach it led to no signal, so I suspect the piezo might be dysfunctional as well.  Unfortunately, in my poor attempts to get this working, I pulled a bit too hard and severed the two wires... but ah well, those can be soldered.

Here are pics of the devastation: http://i.imgur.com/FXj1LK0.jpg     http://i.imgur.com/hxUdGca.jpg

I saw in a different thread about fixing bass drums on this site that the best strategy was to just not even bother with the sub-resonator - just attach the piezo directly to the metal plate, and to kind of put it near the bottom so it's not being hit directly by the beaters.  This seems sound to me, but I'm not entirely sure how to go about a few things.

1. Where would one go to get a replacement piezo?  I looked around online but couldn't find it exactly.
2. How does one attach the wires to the piezo and the metal plate?  Is it just one wire on the piezo, one on the plate?  Do you just use electrical tape, or some sort of glue?
3. Similarly, how do you attach the piezo to the metal plate?  Is this some heavy duty tape, or glue?

Sorry if this has been posted elsewhere on the site - I looked around but couldn't find anything.  I appreciate any help you are willing to give!
Thanks,
Ryan

The piezo comes with wires attached. Buy a couple of 27mm piezos on eBay - they are quite cheap. The wires are then soldered to the socket - or to extension wires soldered to the socket.
The piezo (with wires attached) is then glued or gaffer taped to wherever you want to place it. :)

Agreed, but I would also state to just adhere the piezo to the main steel plate and don't worry about the plastic sub plate. Also, you might want to affix the piezo at the 6 o'clock position on the plate. This will keep it out of direct impact with the beater.

Tacobot:
Perfect, thanks very much for the info guys.  Just a quick question - any sort of glue / tape will work?  I just wonder - with the bass drum taking a beating as it does - if there's an optimal method to make sure that piezo sticks.

Thanks again!

Dear drummers,

   Which is the appropriated piezo's size for Alesis DM10X bass drum: 27mm or 35 mm? Thanks in advance.
