Mincer,
Both are available. The first one as used also called the Carvin AH pickup on ebay (M22 & C22 & H22) and have the 11poles per coil. The H22 is generally what Holdsworth settled on. Here is an auction and photo of H22's https://reverb.com/item/14850458-car...sworth-pickups The second one is a Kiesel Pickup you can find in the new Kiesel HH1X. They ship all HH1X;'s currently with that, but it is better to ask them. I do not know if they made any changes since. I dont remember the pickup name but you can get it from Kiesel if you ask. I can go look at my data what it is called.
Here it is ..... https://www.kieselguitars.com/products/KH12B Alan switch to that as his final pickup which he liked a lot. I saw him live with that pickup in the black a few months before he passed away at Cruise to The Edge. I was about 8 foot away from him at that show ( learned a lot! ). Was a magic experience.
Thanks for this info. I wanted to see the specs to see what pickup was the closest in the Duncan line.
Going on specs alone (not a great way to see if pickups sound alike), it might be close to a double-screw bridge Whole Lotta Humbucker.
