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.
