I need a nut for my series 1bass.
Does anyone have any ideas where to find one?

A call to Alembic will get you a blank nut for your bass. Either fixed or adjustable.

Thanks.
I did email them no reply as of yet.

I've found the best way to get a hold of someone at Alembic is to call them on the phone. They get so much email that a single request can get lost in all of the noise. I try to call them between 10AM and 4PM PDT. If no one answers I leave a message and I usually hear back from someone by the next day. 

Hi Larry,

I got a message from you through Facebook today at 7:30 this morning which we answered at 8:20. Please let me know if you didn't get that reply. I don't see any emails from your address - where did you send your inquiry?

Yes thank you .
