I got the HBA115. I wanted the Fleor, but the shipping on those would've taken longer, LOL, so I didn't want to wait.
I had some issues with the polarity of the pickup. The polarity is flipped compared to Duncans, Gibsons, Suhrs, DiMarzios, etc. But once I sorted it out, I got it working.
It's pretty OK! I don't feel like I hugely downgraded teh 490R it replaced. It kinda sounds like what you'd expect an 8K-ish A5 pickup to sound like. Kind of along the lines of the '59 or the Jazz. It's pretty alright. It's not particularly noisy of microphonic either. Kinda like how people speak highly of the Epiphone Probuckers, I suppose. Not gonna say this is OMG AWESOME, but I feel it's nice that the look of my pickups now match better, and it doesn't look as thrown together, and it's nice to have a decent usable neck pickup sound for the rare occasions where I flip that pickup switch.
I suppose the only downside is I expected the pickup to be hotter. At 8.4K and powered by A5, I thought it would be hotter than the 7.5K A2 490R. It kind of isn't. It's roughly the same. But it's alright. It balances fine if I crank it up (the same way I had the 490R).
So I think the experiment was succesful. I kinda feel curious about trying the matching bridge pickup. It's 16K-ish A5. But I'm no hurry to swap my Suhr SSH+'s out either.
