Fender Rhodes Piano Preamp

 
 

  
Since 1990 we have tested many different pre amps, modifications, “Dyno” circuits and other hybrids and found that the original Mark I topology (Circa 1970-1976) is the most desirable preamp for Rhodes pianos. In these years, the Fender Rhodes pre amps used mini lamps to create the famous “soft vibrato” effect.

We re-created the exact lamp filament effect with modern components and added custom active EQ circuitry based on rare EQ topology that was circulating around Los Angeles in the 70’s – 80’s.

The Pre amp is handcrafted in our workshop and custom built to order. The preamp is offered by application only. Each unit is considered a prototype. The external look of the unit changes as we test different boxes, power supplies and knobs. Price fluctuate accordingly.
