I guessed soapbar because your pic shows one screw on each side, like most soapbars, while your previous one with the Seymour Duncan Ric pickup has a three-screw mount.
The two screws in the pic are only for support while spraying the finish. This way I prevent the vulnerable surface of the fresh layers of lacquer from touching the table.
I'v heard the Duncan pickup in a Ric but I'm curious to know how it compares to other pickups you have used in your builds.
The only other humbucker that I've used in this model is the EY Chinabucker. And I have to admit that I prefer the sound of that one.
But my customer wants this one. The Seymour Duncan sounds great too. Less focussed on the mid low frequencies than the EY, but still a nice pickup.
Plus it is versatile because of the option to split the coils. I am going to equip this bass with a slide switch too: series, parallel, single.
