Once again........ thanks to Vintage Drum Forum, I emerge a victor over my drum problems and I am enjoying the spoils of my victory. This snare sounds PERFECT, now.
I wish I could remember specifically who to think but I don't remember which post it was that I read that tipped me off.
I was searching around and read read reading the forum and someone (thank you, whomever you are) suggested the Evans web site for tuning tips (and posted a link). I clicked the link and instantly recognized the tuning video as I have seen it several times in the past. However, THIS TIME when I watched it, I took note of how he mentioned that the snare must be nice and straight and evenly tensioned. Funny how you'll see different things in the same video, as you watch it over again.
So, I went back and took very special care to make sure the snare was JUUUUUUUUUST right.
It sounds absolutely perfect.
Thank you, once again to VDF. This place is an unbelievable source.
