The new pedal is very different, but is based on the original design to some extent. On the outside it looks very similar... 2 tubes, and all the same controls. The tubes function differently now, the range of compression has been expanded by 75%, the noise floor has been lowered by 50%, the output volume has been increased by 35%, and the pedal has a great deal more clarity than ever before. Its so much better and so wildly different that it really needs a new name... thus, the "Op-2 Comp." It is now a straight up vacuum tube powered optical compressor. It has an ultra fast attack time from its LED light source, but with the beautiful and legendary auto-release characteristics of the much famous LA2A studio compressor. The soft and hard knee controls are also more obvious sounding than in the original Opti-Mu Prime. You can now distinctly hear a significant tonal difference between the two different compression attack slopes.
Its a seriously badass pedal, which I promise to released in the future.
