What type of music are you playing? What sort of pedals and amp? Is there an example of a song that has the ideal neck tone you are wanting?
I'm playing in a band general hard rock and instrumental progressive rock/metal. I use my ibanez mostly for the instrumental progressive rock/metal, my other guitar makes it for 70's to 90's hard rock for now (maybe a SD in the bridge one day...)
My amp is a flextone III and I use often a modded crybaby wah and nothing else.
There is not really a "perfect neck pup tone" I'm wanting, I'm more following my ears than rather trying to imitate a tone I like, but I like Vai's sound, the petrucci sound too (on Black clouds) but this is liquifire and highly processed.
Can you be more specific about what's going on with the PAF Pro, the AN and the PAF Joe? What about them do you like and don't like? What are you looking for more and/or less of?
Paf pro: very good overall, but I'd like to have more punch, more bite and more personality. It lacks of agressivity but I'm not sure I put the right words on my feeling. Really like the open wah sound
AN: way too much damped, doesn't go out of the mix in a band situation with my amp settings (I go out of the mix with either the Paf Pro or Paf Joe).
Paf Joe: Really liked the harmonics and the open wha sound, but in the end it's too bright and too dull/soft attack for progressive metal / progressive rock leads. Much better on a 22-fret guitar for hard rock style.
I used to have a double whammy (DP150) in the neck slot for several years, the higher output, the particular EQ and the ceramic magnet gave a higher punch / agressivity. I liked that punch/agressivity. Obviously my sound was very unique and I liked that but became bored of the overwhelming mids after ca. 5 years.
So the PP is quite good but I'd like something as I tried to describe above. The EVO neck description on the DImarzio website states: "fat, punchy and loud".
The guys at DiMarzio said that neither the GS nor the EVO neck would make it, and proposed the Illuminator neck and the transition neck, I must say that I'm surprised and upset...
The pickup picker never stops to propose the GS, illuminator or liquifire (I had a chance to test a liquifire on a JP6 and was disappointed).
I'd like a tight sound with a great pick attack response and harmonics.
