I built a Partsquire last year with a Vintage 60s RI body and 50s Classic Series neck, really just as a project to explore the Esquire thing. Initially I used the bridge pickup from a Bootstrap Original Recipe set and that sounded great, but I wanted to keep the Bootstraps together as a set so I replaced it with a Cavalier 51/52 Lion. I really dig that pickup. So it was cool having an Esquire in the stable but I ended up bonding with the guitar more than expected - the neck (is “Vintage C” an actual profile?), the weight, just overall feel - and as I found myself playing it more, I was missing having a neck pickup for the styles I usually play. I thought about a mini humbucker and as I was exploring that idea, came across some threads on these pages mentioning the Phoenix Firebird and learned how a true Firebird pickup is different from a mini humbucker. I was intrigued. This post by rigatele was particularly useful: http://www.tdpri.com/threads/cavalier-phoenix-firebird-quick-test.696800/ I ordered the pickup on Sunday, the day before Memorial day, and was expecting 10 days not including the holiday, so I was shocked when it arrived on Saturday, in basically 4 business days. Of course I need to rout the body. I’m not much of a woodworker. I bought a plunge router when I built my studio monitors 5 years ago and haven’t used it since. A little rough, but I got it done. I bought the pickguard from WD Music, cut for a Gibson mini humbucker. I had to file it out to get the Firebird to fit. I wasn’t sure about the orientation of the pickup, so I emailed Rob. He responded within an hour, on a Saturday! (Answer: it doesn’t matter). Wired it up using the existing pots and cap - the first try was out of phase, but easily fixed. The pickup definitely produces more treble than a PAF-style humbucker. I’ve read folks describe it as a between a P90 and a PAF. I don’t know, I think it’s its own thing. I balanced it by raising the bass side and lowering the treble side significantly more than I do with a PAF. Then I balanced with the bridge by raising it, which I should have done in the first place . It sounded good before, but now - wow. The Phoenix sounds great on its own, clean and with some hair on it. I don’t play with a lot of distortion so haven’t really tried that. Together with the 51/52, is just sweetness. Looking forward to showing it off and playing it at a jazz workshop today. I’m definitely a fan of Cavalier pickups. Rob’s customer service is awesome. And if your looking for something a little different, give the Phoenix Firebird a try.
