Very cool. I played a Quantum 4 Sweet Spot for a while. Belonged to the singer of a band I was in. We tuned down a 1/2 step, and then did a lot of drop C#, so the 35'' scale helped. I discovered that their "sweet spot" was centered right where the 36th fret would be. Then I discovered that's where a Rickenbacker bridge pickup sits. Which kind of led me back to Rics after many years away. =) For a few years my 4003S was equipped with just an EMG 35DC in the bridge position running through their BTS pre-amp.
