Well-well ...you all are getting very Alembicious right away. About your sun: keep that thing in mind, he is just fumbling and ...he is getting somewhere. We grown-ups (I'm 47 in age but not in mind) are getting too closed and afraid to set things on their head. The SI and SII's -the original set-ups- were invented by people (Ron in the first place) who dared to think differently on sound (goes as well for guitars as for basses: dont forget you lower guys that Alembic is doin' great work on the high end too). So this is mainly the reason why there are so many bass-players that are hating Alembics: its not just NOT doin a simple Bom in the first place. You CAN do bom but you can definitely go Boom-tchi-Boom-thi-quck-quack-boinbg-triiioong-pock-pock. Most bass-players love just to bom (merely they MUST by their band-leaders).
It's why I said: the Alembic oblige you to choose and to come out of the dark wall of undifined wobling sounds, it's a challenge for your taste and for your playin,
The Alembic is also hated (yes it happens) by studio-technicians, they'll say: listen man, you have too many knobs on your bass. Let's agree: I'm the one with the knobs, you are the one with the strings. So just go bom and I'll shape the sound!.
Brrrrrrrrrrrrr - hatefull in the ears of Alembicians. (I know one guy who said: can't you get a Fender??).
Something about the Strap thing. My Alembic is very heavy but hey friends: where do you think that sustain is coming from? (Les Paul experimented for his first electric guitar ...on a steel bar!).
But for the strap: just look for a good wide, leather strap. It will spread the weight over your shoulder. There is a brand that uses sheep-skin under their straps and they give some comfort to but I'm not feeling to well with it. I'm a bass player, not a sheperd.
Keep on the low side, be Alembicious!
Paul
