Nordstrand Audio not only produces great pickups but also has a team dedicated to the development of effect pedals under the Rocket Surgeon brand. Its latest effort is called Ice Caves, an ambient reverb pedal. Let’s take a closer look…


Rocket Surgeon Ice Caves Ambient Reverb

The Rocket Surgeon/Nordstrand website has a nice marketing spiel about its effect designer/tinkerer “Dr. von Füzzbrauer“, who visited the Ice Caves of the Dachstein Glacier, inspiring the frosty reverbs used in this pedal.

Simple Control

There are four controls on the top of the Ice Caves for the following parameters: Level, Depth, Echo and Brightness. The Level and Depth knobs control the output of the effect signal and the ‘size’ of the reverb. Echo controls the pre-delay of the reverb, whilst Brightness is a low-pass filter that can be used to trim the highs.

Ice Pot & Ambience

The additional Ice Pot works hand in hand with the Ambience toggle switch and controls a feedback loop that either only affects the echo function of the pedal (delay) or runs through the entire circuit (reverb). Alternatively, this function can also be deactivated. With these additional options, you can create some special sounds, all the way to self-oscillation. According to the manufacturer, the function works very interactively, potentially giving you possibilities than your standard reverb.

The company has made a vivid demonstration video, which I have linked below. The pedal is equipped with a true bypass and operates with a current consumption of 90 mA (external power only, no batteries). Incidentally, there is also a trim pot inside the pedal, with which the overall volume can be readjusted. By default, it is set to unity Gain.

RRP – USD 199
