I need to start visiting here more often. This is one of the few times I've gone south of the stickies, as well.
I'm on my 2nd Silo Bass & my 5th Fender Bass VI--to my fingers & ears, they are quite different beasts. I tune them both E to E & use the EB set for my Silo Bass; I've never had any problem with a flabby E like some here have noted. I am currently using a set of LaBella flats, guaged for a Fender VI, on my Fender VI. As I recall the EB set for the Silo Bass E to E tuning are not the same guage as the Fender VI uses.
I got my current Silo used & when I got it, it was strung up for an A to A baritone tuning. I don't know what kind of strings they were & how the bass was otherwise set up, but I could not play it in that tuning--the pickups seemed to be as low as they could go & the strings still kept "bottoming out" on the pickups. As soon as I installed the E to E set, it played & sounded great with no further tweaking required.
Fred, let's see some pictures of it??
