The Crazy Tube Circuit While Whale is a very tweakable real spring reverb (i.e. it has an actual spring tank under the hood, hence the size), with knobs for depth, speed, tone and dwell and three different springs for varied depth. It also features a tremolo inspired by Fender blackface and brownface amps with its own footswitch.
Many excellent YouTube videographers tackled the Crazy Tube Circuit White Whale, see their videos below. We also added it to our list of the Best Spring Reverb Pedals.
Why do you have to struggle for a digital emulation of two classic effects when you can have the real thing! That’s what we asked ourselves when capturing the concept of White Whale. It features a real 3-spring reverb tank along with controls for dwell, mix, and tone to provide the lushest analog spring reverb you’ll ever find in a pedal of its size (17 x 12,5 x 7,5 cm) to experience the ultimate ride of a wave. Combined with its two selectable modes of an all analog tremolo, opto (black) and bias shifting style (brown), the White Whale is all you’ll ever need to deliver old-school surf tones.
 Each effect has its own true bypass function (via the onboard footswitches or remote switching units) so you can have simultaneous or independent operation.  With 2 separate expression pedal inputs you can control parameters like reverb mix and tremolo speed. Classic sound with modern flexibility !
