Hurrah! I have recieved one vote!
Unfortunatley, it was a vote for "
No, he never used flatwounds"

.
I've been trying to emulate his tone using roundwounds and it only recently occured to me that the reason I couldn't get the balance between "mudiness" and "bark" quite right, might be that Bruce was using flats!
Back to the drawing board then, unless anyone else has a different opinion?
