Mine does not have that long circuit board and I don’t see the five position pickup selector switch.

The pickup connections have been altered, and it states:

 “circuit board with Allen Bradley pots, preamp and individual Q-controls”

So from the photos and description it does not appear to be an original Alembic activator set up.

Hello,

I'm the owner of that Activator setup on Reverb
I purchased that set for an upgrade of a Steinberger GR from a seller who described it as all Alembic
the volume and filter controls display the Alembic marking on their respective circuit boards, but the preamp does appear to be of different design, on a blue breadboard with no Alembic marking
I will revise the Reverb ad description and welcome and other info anyone may have about the preamp origins - home-brew from a Stratoblaster kit?

I'm pretty sure this is not a handwired board from us - though we have made lots of handwired boards. One thing is that the IC isn't one we use, and the board has no copper plating on one side in strips - we've always used Veroboard for little one-offs. Now of course we just order printed circuit cards, since you can get a handful made inexpensively.

Sorry I don't have any leads on who made the circuit you have there.

The Alembic boards in the set have Clarostat pots. The filter pot has the preamp,  so there's no need to add a Blaster. Curious!
