The depth of this unit with the included Audio cables are well over 80mm, even though the PCB itself measures about 50mm. This is a misrepresentation of module depth and causes it to be unusable, unless you want to invest more money or void the warranty. Additionally, the white noise (not the hum) the reverb tank picks up while inside the case is as loud as the effect itself. I like my other Doepfer modules, but this is one to skip, unless you want a large, white noise generating module for cheap. The Doepfer tank is about twice the size of the module itself. If you have a Mantis, skiff, or most modern portable cases, skip it. I LOVE the Intellijel Springray in comparison; its tank is about the size of the module & is noise-free in the same location + more features.
