Rockruepel Comp one

Oliver Gregor and Guido Apke, designed and built a puristic and pristine tube compressor. Both have years of expierence as engineers and in repairing and modification of high end audio gear. This lead the two to improve the design of variable input tube and modify it to their liking. The unit is built by and for ears and is built from Oliver by hand.
