Unlock new dimensions in your recordings with the Radial Engineering JCR, a passive reamper that transforms your studio workflow. Engineered with the legendary John Cuniberti's original Reamp circuit, this device lets you breathe new life into your pre-recorded tracks. Want to add grit or depth to a lifeless guitar take?

The JCR not only handles impedance and phase with finesse but also features a three-way filter switch, enabling you to sculpt your sound at the source. Whether you're aiming to tame harsh highs, warm up the lows, or revert to the pure original signal, this reamper has you covered. Built to withstand the rigors of studio life, its robust 14-gauge steel construction and no-slip pad ensure stability even on vibrating surfaces.
