JC Emerald

$220.00

The JC Emerald is based on the preamp of the legendary Marshall JCM800. It has been modified to make it more suitable for pedal/preamp use while staying true to the original JCM800 design. This latest version includes some additional toggle switches to make the preamp design more flexible.

Brite switch on – stock JCM preamp

Both switches off – treble rolled-off

Deep switch on – low-end boost

The intention was to make the preamp more useful for bass, but it also makes it more flexible for guitarists that want the classic JCM gain structure but without the aggressive treble of the original circuit or that want more heft behind their tone.
