So recently I decided to go the way of EMG after skimming over some reviews and was absolutely disappointed when I purchased the EMG P active pick up. Even with a BTC control I just couldn't tame that pick up or get any warmth out of it at all. I could however see it being useful if I played heavier music or music where you really need to be at the front of a mix in a upper mid sort of way. Anyways, after that purchase I was hesitant to buy anymore EMG stuff especially after seeing that I couldn't find any solid reviews of the new X series or Alinco pickups. I ended up just taking a risk and getting it anyway and I must say I was impressed. I bought the EMG PAX pickup with a BTC control and it sounded SOOOOO much better than the old P to me. The X-series really makes a difference with the tone and brings back down from a "I'M GOING TO RIP OFF YOUR FACE AND MURDER EVERYTHING YOU LOVE" to a "I'm going to cut through the mix in a nice way!" The PAX not only has that new x series pre-amp but it also has alinco magnets! Now be warned, when EMG says "vintage" in the PAX description it honestly doesn't mean vintage. I wouldn't buy this if you like very fat or extremely round sounds as it just isn't built for that. It does give a nice variety of sounds that the previous P just couldn't though IMO. I use it for quite a few different styles of music and honestly it's a very versatile pickup where I couldn't find that with the old versions. It also sounds great across the entire spectrum of the bass, no SUPER LOWS just to have brittle highs that wouldn't cut through the mix no matter how high you cranked your mids. Overall, a great pick up in my opinion and it really broke that stereotype of sterile electronics that EMG seems to have.
