Im undecided in where the tone sits on mine.
I would have also said more P than J, but my Geddy Lee sig has recalibrated what a J can do in my mind.
The stock pickup isn't the highest output, but has enough punch to sound convincing. Our vocallist likes it! I too think a quarter pounder maysound nice, but would ruin the character of the tone.
But overall I love mine. Sounds unique, looks fantastic (I have the blonde) and feels great. Never bothered sticking it on the scales because I eat my spinach and it bothers me not, but I'd say just slighly North of middling for weight.
Neck is closer to modern P than J, but not super beefy.
Finish is first class, aside from slight rough edges to the pickguard on mine, and the nickel hardware is to die for.
I'll be gigging with it Friday, thats how much I like it.
