Henretta Engineering Emerald Prince Preamp
The Emerald Prince is a preamp circuit modeled after the famous Echoplex EP3 preamp. The 2” x 2” box can squeeze its way onto any pedal board. An Internal trimmer controls output volume, with just a touch of boost. An internal bright switch toggles between a bright mode that provides clarity and a unique mid-range character and a dark mode that fattens the sound while maintaining punch and clarity.
