Looking for a tremolo

Hello everyone,

I write music for a Croatian instrument called the tamburica (or tamburitza), it is a stringed instrument played with a pick. I have been looking high and low for a tamburitza (also sometimes called tambura) sound. The major problem I'm having is because notes that are quarters or larger are tremoloed, but I can't find any audio sample that has that. I've found a lot of soundfonts that have strings tremolo, but it's more violin stuff. Mandolin hasn't been much help because usually it's just one pluck of the string per note; I need more than that.

If you want to hear tamburitza music, simply type in tamburitza into youtube, there's tons of it. Now if I can find that sound, I would be most appreciative!

Thanks!
