Vintage Simmons Drums (UK) Users Group

Hello everyone - 

Last night in the middle of a show I was performing at, my SDS-8 bass drum stopped triggering.  I checked the chord and the module and both were ok, so I know it is the bass drum.  I have had these pads for about 4 months and have performed live with them probably 4 or 5 times with no problems.  I know very little about how these were constructed, so not sure how to further diagnose the problem, what to look for, and even how to fix it once I find out what the problem is.  Can anyone help or point me in some direction?

Thanks,

Nick
