Even though the Crawler and Emerald neck models share an AIV magnet, they are VERY different beasts. The Crawler is rounded with a duller bottom end. It had a nice tone but no cut tended to get a bit muddy under reasonable amounts of gain. I really didn't like it at all so sent it back. I like a PAF tone but I like it a bit brighter and with more cut. The modern wire does that on the Emerald and the AV magnet does it on the Holydiver. That was certainly part of it but it couldn't have been everything because I now use a neck pickup with an AII magnet and vintage wire and it's fine.
