i have a jp6 but just found a used luke for dirt cheap. im familiar with how the luke plays but not really with how it sound (when i play them its in a guitar center and with all the crap amps i end up using a roadster and then it just sounds like a rec because i havent spent time playing with subtleties). i own a jp so a comparison would be much appreciated to see if what id be getting into is worth while. thanks guys.
