DeltaLab memory expansion

Ah, THE early echo unit of American spacerock bands.
The tabla loop on F/i's "Space Mantra" is an Effectron
and the space electronics was all ARP 2600 and Effectron
up to the "Paradise Out Here" album.

Doug Walker of Alien Planetscapes still carries an Effectron
in his effects rack and uses it to this day (so it's blessed by the best).

Definitely "Spacerock Tested".
