These work with Dim Pro and Rapture, for those who don't have Kontakt (there is already a Kontakt version as well). These are "amped" samples, meaning they were recorded through a tube amplifier (Fender Twin Reverb) so they're deliciously crunchy. 16 velocity layers on each, which is crucial for such dynamic instruments whose character changes dramatically between soft and hard playing.
Both are included in the summer sale: Wurli is $19.50, Rhodes is $29.50.
