It never ceases to amaze me at how some are just blissfully ignorant to details that most players would immediately notice as vastly different.
If you can't tell the difference between Pepsi and Coke then you might as well drink that sewage, RC.
Comparing Pepsi to Sprite is like comparing guitars to piano's.
An 87' Radius is as close to a JPM as it is to a JS
, if the JPM was 22 fret.
R - JS
Ultra D shape neck - JS
PURE C SHAPE
430mm radius - 250mm radius
Jumbo frets - Medium would be generous
Scarf joint [2 piece] neck with truss rod under fretboard - pure 1 piece neck with rear routed truss.
In fact the only similarity is they're both 22 fret with rosewood fretboard.
body is 1/8" smaller in all dimension, the arm and belly contour are nearly 3 times as wide and slimmer, the lower cutaway is deeper for better upper fret access, and the horn is slimmer. Of course the control layout is different and the JS
has the angled jack but who cares, right?
An R is heavy and clunky in comparison to the much more refined JS
. If Ibanez chose to switch R body cuts to the JS
because it was a much better design or because it was more prudent to only machine one body type for both series will never be known, but all R bodies were changed to JS
profile in 91', after which time you could certainly argue more similarites, but not in the neck, ever.
