GA3. Organ.sound.

Derrick. Can anyone tell me if it is possible to get the well known sound of Klaus Wunderlich on the GA3 organ.
If anyone has done this would you please let me know of the settings, I have been trying for a long while now
and I am no further on, I can't seem to get near it.
Is it possible to get a disc with this sound setting from anywhere.
Thank you anyone who may be able to help .
I would also like to thank every one involved with the infomation given on the forum there is some wonderful
info available and so much to learn, best thing I did was to join the club.
Thanks again Derrick.
