I've had a JB\Jazz 7 set in my Mayo since I've had it and I've always liked the basic overall tone. However lately I've been thinking of a change. The JB in the bridge is just too damn flubby. I want more definition and attack, especially on the lower strings. I'm not that fussed about the Jazz in the neck either, for mainly the same reasons. It's got to be a decent all-rounder. This guitar is my main and I use it for everything from sparkly jazz/blues cleans through to more gnarly drop-tuned metal stuff.
So I was thinking of the Holy Diver set. Seeing as I only ever seem to read good reports on them. And plenty of people say that they're a much better alternative in the 'JB family'.
The guitar is mahogany body, flame maple top, mahogany neck.
First post here so hi everyone!
The Holy Diver is based of the JB but its tighter, clearer and less bright/treble. It still has the same overall tone though so I don't think it will suit what you are looking for. It has a compressed feel so the low strings are tight but the bass response isn't very fast. In a Mahogany body/neck you will need a ceramic pickup do get the definition you want.
I am getting a set of the new 7 string Lundgren "The One" pickups to replace the Holy Diver in my Schecter USA so I can't let you know how they sound once I have them installed.I wouldn't recommend the HD neck. It doesn't pair up with the bridge in output and tone. An Emerald is a much better match.
I would recommend the Nazgul if you want a lot of attack and definition. Its tight and very clear but the rest of the strings stay thick right up to the high frets. A lot of pickups overcompensate for the low B which leaves the rest of the strings thin while other pickups have a muddy low B string to keep the rest of the strings thick and full sounding. The Nazgul is a very good balance between the two and perfect for lead and rhythm playing.
