Finally scored a vintage Univox Phase III. The nut wasn’t filed down properly though, the toggle switch was replaced also. Analyzed the pickups, compared them to my test 3 clones on my Cobain Mustang and the other Phase III sunbursts I analyzed. The loaded resonant peak is lower down to 2.83kHz. Same as my test 2 clone but on 52mm spacing. I think sound better than the other Univox Phase III’s I tested at 2.99kHz. The lower bass range is definitely better. So the range making will be between 2.83 and 2.99kHz. But I love how the lower peak 2.83 pickups sound. Not as piercing as the others.
