Re: JB in a Hollowbody
Welcome to the forum.
Never tried a high output HB in a fully hollow (Acoustic Electric) guitar. Have tried a Gibson Tony Iommi HB in an Epiphone semi-hollow.
As you suspect, high output pickup + big air spaces = howling feedback. The tone is none too clever either ... until you down tune to C#. Then, things get downright evil in a Geordie of Killing Joke kinda way.
Younger forum members, Google or Wiki to find out about KJ.

Re: JB in a Hollowbody
If you like the hollow body sound, you want PAF's to bring those qualities out. JB's are not the PU to be using. Just a bad idea.

Re: JB in a Hollowbody
Depends on the hollowbody.
On some, they will feedback no matter what you do. There are things you can do to limit that.
I have two fully hollow Corts. One has a JB and it does just fine, sounds fantastic, and the only feedback is nice controllable infinite sustain.
On the other, even a PAF made it howl badly, with a totally clean tone. I was able to get rid of a lot of that by 1) using rubber tubing instead of springs to mount, 2) putting foam between the bottom of the pickup and the back of the guitar, 3) putting a very thin adhesive foam I got at Hobby Lobby (and that I use for a lot of music related things) under the edge of the pickup ring so that the pickup ring is isolated from the top. That guitar now has a CC in it and, while you certainly can't play metal with it feedback wise, you can use high clean volume or light to medium gain and it is very controllable.
I don't care for PAFs in the bridge of anything. JB works just fine. It isn't a hot pickup in spite of what people claim (confusion about DCR and output will never go away will it..........), it is just hot enough to match a light wind PAF in the neck volume wise. In the neck of the first Cort I mentioned above, I have a Lollar Firebird neck, which is a 6k mini bucker using standard 42ga., so not exactly hot.
I also have a JB in the bridge of my Gibson CS-356, which isn't fully hollow, but sounds very similar to a fully hollow guitar. No issues at all with feedback.

Re: JB in a Hollowbody
What some of us are referring to is a hot wind, which does not necessarily mean high output, and many of us here know the difference. 16K is a hot wind. To us PAF lovers, a 16K PU with a relatively high-output magnet is a hot PU. From the metal side of the fence, it may seem moderate, even suitable as a neck PU.
You call a 6K mini-HB 'not exactly hot"...is this contradicting your preaching about equating resistence with output? Why even mention the 6K if it has nothing to do with it being hot or not? :14:

Re: JB in a Hollowbody
JB is not a hot wind. It is thin wire. Thin wire accounts the high DCR.
I don't play metal. I dont use much gain at all. Don't lump me in with the "you can never have enough gain and you can never turn the mids down far enough!" crowd please.
I use low gain and a whole lotta mids.
JB is not hot, not a hot wind, not a hot magnet, not hot. It is barely hot enough to equal out volume wise with a '59 or jazz neck. That is nothing like a medium output bucker like a Breed or AT-1, much less a high output bucker like a X2n or Super 3. Breed or AT-1 can overwhelm a jazz neck, X2N or super 3 definitely so. Not a JB. I have to put the JB close to the strings and back the jazz or '59 neck off to balance.
I also mentioned 6k with 42ga wire, standard a5 mini bucker. That DOES tell you something. That is different than 6k with 41 or 40 ga wire, or a ceramic or A8.

Re: JB in a Hollowbody
No arguing please.
appreciate all the input. I have a reverend Pete Anderson. It's a hollow with a block running from the neck, right under the bridge, then to the tail. The pickup cavity is open.
It has the stock p90's and they only feedback if I use a higher gain pedal like a lovepedal e6.
I already have a set of uncovered jazz/jb that I'm gonna mount to dogear rings and give it a whirl. I also plan on coil splitting both of them as I like the sound of split jazz and jb's.
I'm mostly playing rock and blues, nothing metal so I don't need a wailer.
I have to agree the jb isn't a high output pickup but has a nice smooth output for rock. We'll see how it goes. I'd try 59's but I've always been on the fence abo it them.

Re: JB in a Hollowbody
haven't tried a JB in a full hollow, myself.
the feedback issue has many other guitar-related variables to consider.
the short version is that i wouldn't put a JB in there unless i was aiming for sonic chaos (like funkfinger said, and +1 on the welcome).
the JB seems to colour a guitar's natural sound considerably, which (regardless of the relative amount of turns on each coil and the thin-ness of its wire gauge) i refer to as being a "hot" pickup and good for assaulting preamps;
i believe we can all agree on that?
as you can see, it is wise to mention one's amp and stylistic leanings when asking open questions in the pickup lounge...

Re: JB in a Hollowbody
It isn't really the pickup feeding back, it is the top and back on your guitar feeding back. The pickup just translates that vibration to the amp.
