In the words of JHS Pedals:

Have you ever ridden the sonic waves of a vintage Fender
blackface or Vox tremolo flowing like water from the speaker? Then you
know that this kind of tone can make you feel like youre sailing on a
million dollar yacht. The Tidewater Tremolo faithfully recreates this
beloved amp tremolo with a warmth and character you would only expect
from a vintage amp. With simple controls and a small footprint, youll
be sailing the high seas of tone with the Tidewater Tremolo.
