Shimverb Pro has the heritage of Shimverb. Moreover, we have made improvements on it. Shimverb Pro uses floating-point DSP chips, giving you a much wider space of development. We have been through countless days and nights of experiments and algorithm modifications. The result is to make significantly improvement on the Shimmer and the Reverb effects. Shimverb Pro assembles five reverb effects including Room,Hall,Church,Plate,Spring, giving you a different experience of sounds. It is equipped with Decay knob which can adjust the room size for the reverb effect. Shimmer function adds a new feature------the combination of 5 switches and an Octave button, which creates a different effect and bring more excellent sound to your music. In addition, Shimverb Pro has separated Shimmer footswitch and Dry/Wet knob, Hi Cut/Low Cut function, stereo input and stereo output, all these new features are going to help you create a brand-new musical journey.
