I have a mint SF-2 that I was saving To maybe use for Monte. It is a killer bass when using an SF-2 with it. Then it becomes pretty much a heavily ebony'd bass with more or less SII electronics in it, a perfect combination. But Monte is another players/Alembic Club member's bass, so I have entertained trhe idea of just selling it. $700 and shipping anywhere in the US, and guaranteed to work perfectly. I believe it has zero rack rash, as I am anal in installations and use plastic washers and bolts that do zero damage to the unit. I seriously will probably quit using my F2-B preamp. Both units are newer style, hardly used at all, and mint if I remember right. Electronics are not like woods, where aging is a positive. The newer tech, the better in my book, but I maybe wrong. Since Alembic uses NASA grade components, they seem to last forever, so old is maybe fine. Current retail on all these units are $1,675. Well, they have always been designed for the professional in mind, so . . . I'm certainly in no rush to get rid of anything right now.
