Re: EDP and a BIG burst of static/hiss

First, I want to thank you all for your excellent role as "Gibson customer
support" and for all the good information.  Tonight I shall (once again)
open up my EDP and this time attempt to clean all the contacts.  I only
reseated the eproms, and upon finding the bent pin, I figured that was
obviously my problem.  When it worked after that, I thought I was done.  I
didn't even bother with the memory becaues the fault seemed so obvious.

Yes, this seems like it could be the reason for the hardened silicone.  It
just seemed a little excessive.  I've never seen a device with as much as
this one has.  I wasn't saying this was a possible flaw, it just seemed
odd.

Thanks again kids.  You loopers never cease to amaze me.
