Radial Engineering Reamp JCR – Passive Reamper with Original Cuniberti Circuit

The Radial Engineering Reamp JCR is a premium passive reamper that lets you send prerecorded tracks from your DAW back into guitar or bass amplifiers for authentic re-recording. Built around John Cuniberti’s original, custom-wound transformer and 100% passive circuit, the JCR delivers unmatched tonal integrity—making it a staple in professional studios for creative tone shaping, amp experimentation, and mix enhancement.

Key Features

• Original Cuniberti reamp circuit: The industry-standard design with custom USA-made transformer for pure, musical tone.
• Flexible I/O: XLR and 1/4" TRS inputs (parallel-wired), plus a transformer-isolated 1/4" instrument-level output for amps and pedals.
• 3-position EQ filter: Low-pass to soften bright amps, high-pass to tighten muddy lows, or flat for uncolored reamping.
• Reamp-focused controls: Variable output level, mute switch, 180° polarity flip, and ground lift for eliminating noise.
• Road-tough housing: 14-gauge steel chassis, I-beam PCB, book-end protection, and non-slip pad for stable placement.

Customer Benefits

The JCR allows engineers and producers to perfect guitar or bass tone long after the performance is recorded. Swap amps, reposition microphones, add pedals, and experiment freely—without needing the musician present. Its ultra-clean passive design ensures the reamped signal feels natural to the amp, just like a real instrument.
