I don't have a GK pro to test, but do have the original GK (Cypress), as well as a Cordoba Fusion Orchestra Pro.
The Fusion comes in different wood combinations, and is considered a crossover guitar. Mine is Spruce/Rosewood, and the same can be had in the GK Pro I think.
So perhaps this sound sample of my Fusion will help. The guitar has an onboard pickup, but I'm not using it here. I'm using the iRig acoustic you see clipped to the soundhole. The only thing I've done to modify the original signal is add a bit of Reverb after the fact.

Hope that helps,
