The silhouette bass guitar (SN # G07272) arrived via fedex this morning (On a Saturday!) I am on my way to register it but I had a couple of questions.  According to the color chart there is no purple offered any more.  I know it's purple but in case an interior decorater asks, what color is it?  Also, is there any structual difference between tuned A to A and one octave down?  Or are they just different strings?  What are the gauges for both tunings you recommend? (Super Slinky Pink)  Finally a DOB would be nice.  This gives me 4 silhouetts, a Steve Morse model and the silhouette bass.  I'll try to post a picture soon.
