Electric Piano Preamp - MKI



 
Preamp Direct Out Audio Tests .wav 44.1 - on a Stage Piano from 1973

 

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, best sounding preamp for the instrument. In these years, the Fender Rhodes pre amps used mini lamps to create the "soft vibrato" effect that fades in and out. We re-created the exact lamp filament effect with modern components and added custom active EQ circuitry and additional (- 18v) dc voltage and (+18v) on top of the original (+24v) for super quiet audio path. This custom EQ circuitry is a re-creation of an ultra rare EQ topology that was circulating around Los Angeles in the 70's - 80's and used on Steely Dan records.

The Pre amp is handcrafted in our workshop and custom built to order. Currently offered by application only. Each unit is considered a signature prototype. The external look of the unit changes as we test different boxes, power supplies and knobs. Price fluctuate accordingly, starting at $1000.
