Eastwood Univox Phase IV Pickup Analysis- Not close to Vintage specs at all

Posted on by

Analyzed some Eastwood Clone Phase IV bridge pickups that I just replaced with my first Univox Clone test. Eastwood pickups were okay, been playing them for about 2 months now, just didn’t have the feel of the vintage pickups. Not bad, just not univox tone. My analysis confirmed it. The resonant peak is lower at 2.7kHz loaded vs the 2.99-3.13kHz range of the Vintage pickups I tested. Not sure what’s inside it yet, but I’ll get to it eventually. Measured specs. DC 8.4kHz, Inductance 5.07H, Measured Capacitance 124pF.

The installed first test Univox clones are a beast. I definitely have that feel. The HM2 sounds a lot more brighter. My waxpotting is a success, I’m able to drive the HM-2 a bit louder. Which reminds me. I’ll inspect some HM2 EQ analysis and design a pickup that would go great with it. I think HM2Cult on youtube does great analysis of that pedals and a ton of clones. Can see if I can cater a pickup’s resonant peak to match the eq.



Cobain Univox Pickup Clone 1.9 @ 2.93kHz

Successful clone of Kurt’s Univox Phase III pickup. Resonant frequency closely matched. The Donlis Alnico magnets were pretty strong at around 700 with slugs at 270. The magnets from Philadelphia luthier were only maxed at about 600. This is going into Cobain Mustang #1 mustang v3. I will cut the bottom part of humbucker ring and align it the way he had. This is the same 50mm spacing on original Univox, so the placement of treble strings will not line up at all. He also tilted the bass strings more towards bridge. Will try to align as much as I can. This time I’ll have to angle the whole pickup instead of angling from humbucker ring wholes. Can’t wait to hear this.
