Congratulations with a very special bass Alan, although I personally prefer the look of 'natural' wood on Alembics, this is actually starting to grow on me, nice!

Bsee, it's a three position switch. It clicks quite securely in the middle and stands straight up - that's the flat setting. I don't think you'd have any trouble hearing by the tone or feeling it by the switch position.
 
Alan: what a beautiful burst finish!

The more I play the Europa, the more I truly appreciate it.  For me, it is the ultimate bass (uhh, other than an Europa with Series II electronics!).  I play it every day now, and it practically plays itself.  Smooth, effortless, like my Spyder.  And the tones are just absolutely astounding.  I can get Jaco tones, Geddy tones, Precision tones, you name it.  Yeah, it cost a wad of cash, but it's worth every penny.
 
Thank God for Alembic.
