I put these in a Strat style body.  First set of Alembic Tele-sized pickups I've owned.  Really enjoying them so far.

Think I'm going to try and put an Alembic Strat-sized pickup in the middle position on a mini-switch (on/off).

There's just a pickup cover in middle position at the moment.  Edit: I put the Strat-sized pickup in today (2nd pic).  Liking the additional options.

I don't have the Alembic filter to go along with these, but maybe can get that down the road. 

If you don't have alembic electronics in the guitar, are you using them passively or with another type of active electronics?

Using with a Jtex Combinator at the moment.
