The Radial Reamp JCR is a passive reamper using John Cuniberti's original Reamp circuit and custom US-made transformers. Send lifeless direct tracks from your DAW back into a guitar or bass amp, introduce effects at mixdown to an already-mic'd track that was recorded dry, experiment with mic placements...the possibilities with reamping are nearly endless. The Radial JCR adds a three-position filter switch to change the tone a bit before the amp, with the middle position reverting back to the original Cuniberti circuit.
