"This rare effects box produced by Shin-ei (Japan) in the late 60s or perhaps early 70s includes five controls in addition to the on-off switch."

They are as follows:

  • A mode dial that selects low pass, band pass, or high pass
  • A peak dial
  • a gain dial
  • a low range/high range switch to select the frequency range being filtered
  • and an up/down drive selector that controls the direction of the filter sweep

"It is powered by two 9V batteries which are very easy to access. The bottom swings out after loosening the easily turned thumbscrews."
