So, I've been wondering about this oak rosin being sold on gregorianstrings.com. Is this the same recipe that I hear the bass players of the 60's and beyond swore by. Are there other recipes that are/were probably as good? And finally, if it's so great (which personally I think it is) how did oak rosin sort of fall off the face of the earth only to resurface in the past few years? Thanks for the input everyone.
