Using Garageband '06 presets in Garageband '11?

I recently upgraded to iLife '11, and while I really like it overall, I'm missing a couple guitar tone presents from Garageband that are nowhere to be found in the new version. I still have garageband '06 installed on a bootable external drive, so is there a way to move some of the presets from the older version to the new version? I've tried finding the location where they're stored, but haven't had any luck to far.

I know I could probably spend some time tweaking settings in Garageband '11 to get roughly the same sound, but if there's a way to use this preset that already exists, I'd rather do that.

Thanks!
