The A2 Hybrid is great. I bought a homebrew Hybrid from another member years back and I can't recall whether it had an A5 or A8 in it, but I found it a bit thin and fizzy despite other positive qualities. Sat in the parts drawer for a year and a half or two until I was looking for something to better pair with my stock (A2) Phat Cat in the neck of my V. I had a spare A2 magnet laying around (actually I have lots of them) so I thought it was worth a try. The original hybrid was A2 so I thought it worth a shot.
It pretty much solved all my previous issues with the hybrid, while still retaining the characteristics I enjoyed. It still has that crazy singlecoil-esque articulation, but with a bit fuller body and softer highs. The fizz is gone. It successfully bridges vintage and modern better with the A2, at least to me. Whatever was in there before was too aggressive.
