Did Alembic at one time offer a magnetized interchangeable fretted/fretless fretboard on one of their basses? The idea came up on a Chapman Stick forum I belong too and I kind of remember Alembic having made one a long time ago.
There are one or more previous threads about that bass. I think it was a Spoiler; and I think we saw it on Ebay.
I thought I remembered something about this from years past. thanks Dave.
Here's (http://club.alembicguitars.net/index.php?topic=3407)a previous thread.
That's it Elwood. So, the answer is no, Alembic did not offer this as an option; this was a modification done by others.
