The White Whale V2 is a fully-fledged analog spring reverb and tremolo circuit, inspired by classic American amps of the ‘60s, crammed into a beautifully compact pedal enclosure for your board. The V2 simply packs more options and a bigger sound into a box of the same size – more features, same board space!

Capture those surf-worth ripples and metallic twangs at the stomp of a switch with multiple modes, flexible effect ordering, and more – totally rad!

Key features

  • Real, analog spring reverb and tremolo sounds in compact pedal enclosure
  • 3 different flavours of spring reverb (long, short, medium)
  • 3 types of amp style tremolo (harmonic, optical, tube bias)
  • Reverb and Tremolo section can be operated completely independently or in series
  • Change FX order: Tremolo into Reverb or Reverb into Tremolo
  • Compatible with expression pedals and tap tempo footswitches, including the White Whale V2 Remote

Here’s what Crazy Tube Circuits say:

The 3-spring reverb tank assembly housed inside White Whale’s enclosure has remained the same, but Crazy Tube Circuits has upgraded the power amp driving the springs for increased headroom and wider frequency response. Following the signal topography of vintage units, Crazy Tube Circuits has also upgraded the dwell control to allow users to dial the right amount of signal that goes into the springs for a mellower or splashier reverb sound.

Real spring reverb found in 60s American tube amps and external reverb units featured a tube power amp driving the spring assembly via an output transformer, so Crazy Tube Circuits has delicately tuned an analog circuit to emulate the tube and output transformer saturation that was produced on higher dwell settings.

The tremolo section has also been upgraded to feature harmonic tremolo, besides the opto and tube bias found in the previous incarnation of the ‘marine mammal’. This hypnotic and mesmerizing effect originated on certain models of the brown and blonde era amps and does frequency-based modulation by shifting between high and low frequencies compared to the amplitude-based modulation (opto and tube bias) that shifts between volume levels.

Crazy Tube Circuits made sure to include the two most significant variations of harmonic tremolo, as found in the original amps, that differentiate in the range and sweep of pulsating frequencies. The depth control sets the intensity of modulation while Crazy Tube Circuits extended the range of the speed control beyond the span of vintage amps to maximize users’ creativity. The volume control will boost the signal if needed, even in the hardest throb settings.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.

Tremolo

A tremolo pedal modulates the volume of your guitar signal up and down in a rhythmic pattern, creating a pulsing or wavering effect that can sound vintage and hypnotic or sharp and choppy depending on the settings. It’s one of the oldest effects in guitar history, famously used on classic amps from the 1950s and ’60s.

Most tremolo pedals let you control the speed, depth, and wave shape, allowing you to go from smooth, subtle swells to intense stuttering tones. It’s a simple but expressive effect that adds movement and character to your sound.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
