You might try Fork's Drum Closet. They have some of these in stock at their Nashville store. Great folks to deal with. Check their website or give them a call.
Musician's Friend and Music123 IS Guitar Center. Interstate music seems to have the best prices around....I'd try them.....
You know, I should have thought of Fork's. A fellow drummer friend of mine in Tennessee shops there all the time. I haven't been there since 1980 or so.
I just found the heads in stock at Interstate Music and ordered them. It's strange that Musician's Friend, GC and a few others don't appear to have them on hand.
Thanks for the quick responses and suggestions!!
For those interested and who haven't used these heads, I'll report on them when I get them. I expect a warmer fatter tone, but will be looking for response and range. Stay tuned............get it???Laughing H
