The UK distributor simply didn't respond to my emails so the price came from various dealers. They presumably had more luck with the distributor, though I did come across one dealer who had recently stopped stocking DiMarzio because their UK distributor was so awful.
The Emerald neck pickup is unusual one. The alnico 4 magnet helps to keep the pickup quite PAF in nature and the tone is really sweet. The 43AWG wire seems to keep things a bit tighter at the bottom end than 42AWG so it retains clarity even under a lot of gain. It's one of the few Bare Knuckle pickups I would have again, if it weren't for the extremely high cost. The Crawler bridge model is the other one. That was an awesome pickup too! Other than price, after trying loads of Bare Knuckles, I just found I could get better elsewhere for less money. The Super Distortion is better than any ceramic pickup I tried from Bare Knuckle and the Classic '83 from The Creamery is miles better than the Holydiver. On top of that, the Creamery '87 set is better than any alnico 2 pickup that BKP do and it's also better than the Seymour Duncan Slash set. Once I discovered that Jaime at The Creamery and Allan at Catswhisker will custom make anything I want for between £60 and £80, there was no point in spending Bare Knuckle money. Jaime has already made me a version of the BKP Abraxas as well as a couple of designs I came up with myself. Allan has made me a tweaked version a Gibson 498T and an Emerald with an alnico 2 magnet before. In every case, the pickups were excellent. I actually received this latest pickup from Allan in just 48 hours so now I just need the Super Distortion to arrive
