I used the original Wally Reference and now have the new one from JR Boisclair who is running Wally Tools with Wally's son. Both are excellent with the new Reference assuring the headshell is parallel to the record in all dimensions - assuming your tonearm has VTA and Azimuth adjustment. You still need a protractor to do the alignment.
