there is no higher compliment from masta'c, in my opinon.
you should see one of the back burner projects I've been working on. I have about 18 JB models that I've been going through, collecting readings (resistance, inductance, and capacitance). ranging from a nylon bobbin double cream The JB Model (with some help from another dedicated pickup aficionado) to JBJs to TB4Js (even a TB4G) to the 90s label to the new labels to a Antiquity JB (with some help from a totally different aficionado) and even 2 fairly recent Custom Shop JBs. been talking about and wanting to do something like this for several years.
just had it since yesterday, so still running it through some paces. official review will be up next Wednesday. it does conjure comparisons to the WLH in a few respects, although a little more open-sounding in the bridge and even more control in the lows of the neck. the bride has 3% offset coils and the neck has 1% offset, which can both fall as much to standard tolerances than to an intentional choice.
