All I know is that I'm excited to try them out when my Monarchy ships
1) That is most likely correct, the new Sonic Ecstasy pickups are rectangular and will not fit in a cavity that is been routed to a smaller size in the corners.
2) Both the Sonic Ecstasy bridge and neck pickup are labeled as F-Spaced. This means that the pole pieces on the neck pickup will be spaced apart the same as on the bridge pickup. If I had to guess, this was done so the same cover can be used on the bridge or neck pickup by rotating it 180* (heck, the entire pickup could even be the same, just rotated/wired differently)
Please let us know your impressions when your Monarchy arrives!
Fender spaced. (vs. Gibson spacing.)Did you mean F Spaced? I believe so. F Spaced is for floating bridges. I believe the term means "Floyd" Spaced but I could be wrong
Also the original Majesty were basswood with mahogany. The Monarchy series are all mahogany. So comparing the two Majestys may be interesting as well
Fender spaced. (vs. Gibson spacing.)
The Majesty and the Monarchy don't share the same electronics, so there's bound to be a bit of deviation among the two. The Illuminator set is quite differently tuned compared to the Sonic Ecstasy set. A good comparison is between the Majesty and the Artisan Majesty (same pickups, different wood cocktail). No difference at all if you'd ask me.
Pretty sure the pickup cavities for the EBMM model are the same as the ones for the SBMM model, and that the pickups will perform great on the SBMM model (if not identical to the EBMM). They sound quite great on the JP16. Very rich, and saturated sound. At least on one of these true hand-made monsters: CHIMERA | Kourbis Custom Amps
No digital overdrive/distortion effects, or any sort of pedal on it of course. Modulations effects on the FX loop obviously. I sincerely wish every member of the forum and most definitely JP could listen his/her Ball on it. It is only then that you can appreciate the sonic qualities of your instrument.
