The EP-3 was originally released in 1970 as a solid-state update to the previous tube-based versions. It became legendary not only for its tape delay effect, but also for the coloration that its preamp would add even with the echo turned off. -

Peak Atlas DCA-75 or a JFET tester circuit. Aion FX measured the JFETs in an original ClinchFX EP-Pre. He sorts his JFETs and only uses ones that fall inside certain parameters. These parameters are not known, so it’s recommended to get as close as possible to the measured values when selecting your own JFETs. -
