Hi AlI, hope you are doing well. I have studied with Dwight Diller quite a few Years ago as I know this topic has been in numerous threads. Would anybody happen to have any of the Tabs in pdf form from Dwight Diller? I have downloaded the free book from his site, however there may be some more out there from several years back. I believe from Gordon Banks. Thank you very much for your time and consideration. This is much Appreciated. Thank you. Brian Scheinhoft.
