The Spoilers typically do not have a brass sustain block which does make a difference in the tone and sustain. My Spoiler 5 has 3 Purple heart laminates but has less tonal flexibility than my first Alembic, a Distillate (same Europa electronics). Another thing to point out is that the pickup placement (neck pickup being as close as a 1/2 away from the 24th fret as opposed to 1or more, has something to do with tonality (1/2 away from the neck tends to produce more bass I feel). Neither of those electronics packages have seperate LP filters per pickup so flexibility is limited as comparitively to the Signature/Anniversary models.
