JCR Specifications

The Reamp JCR is the latest rendition of the original Reamp V.2 that was developed by John Cuniberti. Careful attention has been paid to ensure the sound and performance is faithful to the original. The heart of the beast is a custom made audio transformer that unbalances the signal and shifts the impedance. Key specifications are, of course, the frequency curve and phase response. For reference, we have also provided a comparison between the original Reamp and the new Radial JCR.
