Hi and welcome mate!
I only have the MH neck placed in a Feline Guitars custom all mahahony with rosewood board downsized, headless, semihollow LP type I got second hand. Ok that was a mouthfull. Anyhow, MH neck, semihollow as the bottom line.
I have not in my life heard such a natural pickup. Far as I heard this is as close to amplifying the string as you hear it acousticly as you will get with a normal pickup. Warm, sweet, defined as nothing else. Especially on the low strings there is a combination of natural low end and that P90 attack and midrange that is really special. Musical and wonderful as all hell.
To the point, it does take gain suprisingly well. I am playing into a Orange Tiny Terror Hardwired with OD in front and with those it can get a seriously wonderful vintage rock sound out there. Actually, tomorrow I will try it without the OD. What I get now however is full, warm, and old school. Is it tight for palm mutes under what should be considered metal gain? No. But it is a freaking neck PU. It is however one of my favorites for old schoold riffing and lead work. I feel a lot of 70s psych rock in there for sure. It even has a certain organic fuzz quality at those gain levels. Out of all my pickups for psych rock and clean this is my first pick. Again, just talking neck here. I really with that guitar had a bridge slot, trust me.
So yeah, short version here, I think these can work for you really well. The set will in all imagination ace the jazz, blues, and psychedelia. Indie rock...I donīt know too much about it, but for post rock it can work wonders too imho. Country? Donīt ask me. Garage...again not too much knowledge (I probably listen to it without knowing), but is that not mostly dirty and nasty? Nasty this one can do in a special way.
If unsure check with the BKP guys, maybe a MQ bridge or similar could be a great way to cover everything.
