Here I go: Tonezone 7 / Air Norton 7 combo in Alder guitar with maple neck, rosewood fingerboard and 5-way switch with positions 2 & 4 with coils in parallel (no tone pot).

I suppose there's nothing more to add to what is already said, a sweeeet sounding pickup with great clarity, ideal for that legato stuff. The cleans aren't wonderful, but they're not bad either. In single coil mode has an "acoustic-like" sound that I love.
I'm sure this pickup will sound great in any kind of wood, really a must for any 7-stringer

Well, the Tonezone is a pickup with a great character, I would say; It's VERY sensitive and reacts amazingly to your picking, with a very smooth and fluid sound when shredding, but it screams like a bitch when you pick it hard or when doing pinch harmonics. And of course, it works damn well for rhythm too, with a bone-crushing bass response. I've read some reviewes saying that the TZ becomes muddy when riffing, well, do what I did (disconnect the tone pot, or get a 1k volume pot for the TZ) and you'll enjoy a very rich and full sound.
The clean sound... In serial I never use it, but when splitted it just sounds incredible, It's the clean sound that I was after for a long time.
If you have an alder seven (which is rare, I guess) put this baby on it, you won't regret!
