Subject: Re: [Simmons Drums] SDS V switches

From: Yves BERNARD <wallacious@...>

Hi,

I had the same issue with mine. I removed the cover of the switch and I put a drop of oil. Still, they work fine. I remember I also put 4 resistors on the switching circuit because when I tried to select a new preset, it didn't change. I can give you some more information about that. I noticed that the voltage on the switch was floating.
But, I have a question : does anyone know what is the factory preset for all the sound cards?

Thanks, Yves

In my case the mechanical switches are definitely the problem - not the 14013 or further down the line. Swapping switches cures the problem here - however I don't have any spares...
