I'd suspected before that the electric piano in the Association's "Never My Love" was Pianet, and I started doing some research into it about a month ago, after listening to Insight Out (the album on which "Never My Love" appears).
In his book The Wrecking Crew, about the session musicians in Los Angeles in the 1960s, Kent Hartman writes that producer "Bones Howe routinely encouraged [Larry] Knechtel to cut loose with whatever came to mind, just like on his memorable, off-the-cuff, one-take Hohner pianet solo during the bridge section on 'Never My Love' by the Association" (p. 224). Although Hartman neglects to capitalize "Pianet," he does identify both the instrument and the player. I don't think his assessment of the song is very accurate, however. There's more of an organ solo than a Pianet solo, and it occurs near the end of the song, not in the bridge. Still, the Pianet is the standout instrument from ~2:53 on.
The documentary film The Wrecking Crew may even show the specific Pianet used. At around 40:05, there's a picture of bassist Ray Pohlman, who is listed among those credited with arrangements on the back cover of Insight Out:
The keyboard on the right is either a Cembalet or Pianet; without seeing the range of the keys, it's difficult to tell, but obviously, I'm leaning towards Pianet. The position of the connections on the back panel (visible just under the neck of Pohlman's bass) indicates that it's definitely an N model.
As a side note: I believe this is the first time I've ever seen the Pianet's key cover/music stand actually being used as a music stand.
