UPDATE:
Forget Calton Cases for Alembic basses!
I sent them an inquiry and heard that a case would be about $1300 to start. I figured, OK. I was then in contact with a guy at Calton named Matt, who asked me to measure the length of my bass as Calton was having "issues" with "some" Alembics fitting in their cases. My long scale Scorpion measures 48-3/4" long, and sent that info to Matt. He then replied that as their bass case "shell" is 49" inside WITHOUT the padding, it's a no go for my (and perhaps virtually every other?) Alembic bass. I guess they are not REALLY "custom cases," then. Nice cases for sure, but are they truly "custom" cases when they really don't make cases for all basses? Just a heads-up to you guys who might be thinking about getting one of their cases. Too bad, as I like their cases, website, and "shtick."
