Electronic phasing takes place when a signal is divided, one half slightly delayed, then remixed with the original signal. This “delay” only occurs at certain frequencies and is referred to as phase shift (when the delay occurs at all frequencies, the effect is called flanging). When the phase shift of the delayed signal differs by 180 degrees relative to the original signal, a cancellation, called a notch, is generated when they are remixed. The FINAL PHASE generates 5 notches, which when moved back and forth across the sound spectrum, for example, produces the classic rotating speaker effect.


The 2009 Reissue A/DA Final Phase is designed by the original designers of the late 1970s A/DA Final Phases using very similar parts and exactly the same parts in the all-analog signal path.  The differences between your Reissue Final Phase and the original A/DA Final Phases are:

– The Reissue has true “hardwire” bypass and the originals did not.
– The Reissue Overdrive (distortion) has been re-voiced to get a more modern sounding distortion, while keeping the original distortion tone and feel by backing off the new Overdrive Control. In effect we have added an “11” to the Overdrive.  As you approach the maximum setting, the bass resonance increases and the highs become more complex.
– The printed circuit board (PCB) has a different layout, but is all through-hole design, using full-size carbon film resistors and precision polyester film capacitors for the highest quality signal path. There are no surface mount components in your Reissue Final Phase.
