I mostly play my Diezels and they can take a bright PU.
vintage output bridge singles can get a bit much with my V30s though or is to drastic of a change if you also play Humbuckers.
But in general i tend to use brighter PUs, since i can still use the tone knob to a certain degree.
Not really interested in any other PU from Bareknuckle right now (other than the RY).
The Custom 5 was a bit dry with a big lowend. I will try it again, but it was very uninspiring with the guitar (especially for lead work) i had it in (same guitar that currently features the Jazz).
I have one (lean bass, almost honky mids, soft top), where i think it will work fine, but in this the Duncan SH-1 59 actually work really well and i kind of wanna leave it as is.
