Built for Mattias Green
Mister Green’s Stereo Spring Reverb Machine is another example of the 235 Tube Spring Reverb Unit, albeit with some features that allow it to be used directly with line level instruments like synths and organs as well as studio devices. By mixing two distinct wet and dry signals a large range of new sounds are available: for instance, distorting the original signal while having a clean reverb.
Achieving this is simple with separate tone controls– a Tilt Hi/Low style control on the dry signal as well as High and Low Pass Filters on the wet signal.
The original case and Tachometer style level meter come from an old U.S. military device and are both in excellent condition even considering they are nearly 60 years old!
