Hey Glyn,
thanks for pointing these out - first time I've checked out Boulder, and they've got some really nice stuff.
The banjo is awesome too, and I also fell in love with the conch shells !.
I'm broke until next week, but I'll be heading over to Boulder on pay day :-)
I'd agree about the mandolin - Boulder if you're looking for authenticity, however I'm tempted to grab the 8dio one for that big variety of more cinematic type sounds.
Very nice !
Cheers - Cliff
