"Vintage-Accurate, 1970s Solid State Maestro Echoplex Preamp with ‘Bright’ early EP3, ‘Dark’ later EP3 and ‘MID’ hybrid-capture EQ… Ideal at unity gain or slight boost with increased harmonic complexity and touch sensitivity.
In the 1960s and 1970s, Echoplex tape echo delay units evolved from tube based designs into solid-state designs. Notably, the EP3 model was a solid-state model and had a few variations and revisions to the circuit. A select number of EP-3 models are highly sought after by musicians for their unique musical tone.
Famous musicians of the era and later realized having the EP-3 in their signal altered their tone, even when the echo was bypassed. An internal secret preamp was at work here, boosting and fattening the signal, along with a slight phase shift that alters mid and high frequency harmonic content providing a transparent warm boost – a truly secret preamp boost in the arsenal of the great guitarists of yesteryear.
But not all vintage EP-3s boosted, some dropped in signal due to the wrong TIS58 JFETs, and some were mediocre in tone being a different circuit revision. So, over a decade ago I did something about it! The Chase Tone Secret Preamp™ Effects Pedal uses fine-tuned circuit components to ensure proper results. It is currently the only authentic replica of the most sought-after, musically transparent signal-boosting Echoplex units."
