I got mine the other day and tried to come up with an effective demo. The sweet spot for me to get the famous octavia sound is key of D solo stuff around the 12 fret with the neck pickup. But it works all over the neck to create interesting sounds. I actually did not do the RO into the BM in the demo, but it adds a nice top to the big muff sound, as does the Octron obviously, but different flavor.
