Roland V-drum Trigger Repair

When a head trigger, Roland or any other brand/build, isn’t performing like it “used to,” it is because one or both components have degraded and no longer deliver the triggering performance it used to.  These two components in a any head trigger system is a ceramic piezo (27mm or 35mm in diameter) and a foam cone (or other shaped foam energy transfer interface). 

These components break down with use (normal wear-n-tear) or damage. 

Just like an oil change in your vehicle that maintains engines performance, you have new engine oil and a new oil filter - they are done hand-in-hand, at the same time, because both the oil and the filter degrade and lose performance in tandem.  The same degrading process occurs with a ceramic piezo and a foam cone interface over time - they both lose their ability to maximize performance as they naturally break down and are ultimately damaged from a beating.

Just replacing the cone, like so many e-drummers do, is like changing the oil filter, but not changing the OIL.  That is just wrong!  Do them both at the same time while under the hood (removing your mesh head)!  Many just replace the cone and then a few months later, ask why their trigger performance got a short-term boost/improvement, but then started to fail again, even though they have a relatively new cone on top of the original piezo.

Do yourself a favor and complete the whole job the first time around!  If you just replace the cone, remember this short essay a few months down the road when your piezo waves the white flag.
