MicMix Master Room Reverb MR-II Chorus 60s spring reverb unit withAnother excellent, long spring reverb with a similar design to the excellent Great British Spring (except these were made in Dallas Great Texan Spring maybe?). Yes, it has a neat and tidy looking wooden case, but inside there are springs in a tube just like the GBS. These MicMix Master Room reverbs are simple units in terms of controls (they are on or off!) but can sound superb with the right input. Another spring we always have in the studio.
