i dont know anything about those models mentioned, but just a word of props for Kent Armstrong, he is a super nice guy and makes a quality product.
Every one of my archtops (5) has a Kent Armstrong 14-pole PAF humbucker. IMO, they are the best jazz pickup out there.
I once had occasion to call Mr Armstrong in Vermont and found him to be absolutely accommodating and quite a delightful person. he is quite the crackup...he was full of quips and one liners - it was an entertaining conversation.
again, i cannot help with what you are really asking, but after reading some disparaging other comments, i thought i should at least share my experience with his handmade jazz pickups, which are superb.
Mike,
Any experience with this one?
