Hi David,
That's fine; the Echoplex also runs at a constant motor speed. One of
the heads (I forget whether it's the record or playback head) is
physically mounted on a sliding track, and you manually move it back
and forth to change the delay time.
You'd probably want to do something similar for a Mellotron tape echo.
It's actually better to have the head on a slider -- you can yank it
and perform much faster speed changes than you could with the
rotational inertia of a motor. And if you move it fast enough you can
even run the echo sound backwards for brief bits. Witness the Tommy
Bolan guitar solo on Billy Cobham's "Spectrum". :-)
