The prototype that you see in the video has a circuit with four N-channel JFET. The input stage is not like that of Jack Orman style, but is more evolved.
The high performance power supply is voltage regulated to maximize performance and minimize the hum.
Preamplifiers and all stages that receiving the first signal from the pick ups has a huge responsibility and must be absolutely quiet to not disturb the harmonics produced by the guitar, as well as to not be annoying when the strings are stopped.
