The Wash adds reverb to the signal and through a complicated network of internal feedback loops, subtle multi-head Binson effect, and what Hungry Robot have coined "ripple effect," It works to add a hauntingly beautiful wash to your signal in ways that can't be accomplished by stacking a reverb and a delay in series. It does all of this while keeping the clarity and presence of your original signal without getting lost in the soup of decay.
The Wash reacts to your playing unlike the common DSP reverb/delays with an infinite sustain function. There is a dynamic quality to it that is hard to replicate with any other single pedal.
This is one of those pedals you can play without needing much else, at least to get a really dreamy sound out of it. Good stuff.
Hungry Robots has been a pedal company that I’ve followed for several years. The wash is truly an amazing reverb all around. It’s super lush and applicable in any scenario with creating music. Primarily for me I use it on Guitars and Synths. The music I make is somewhat electronic with drum machines, Moog synths and guitars. You can easily achieve a simple type of reverb but it easily goes into lush and dreamy landscapes. It’s very easy to dial up a great sound in minutes with The Wash. I don’t know about you but when a pedal sounds amazing, is super versatile and looks good I’m sold. I’ve had many reverbs over the years and this one has been on my board for several years.
