Hi all,
I'm working on designing a looper with buffered outputs, as well as adding buffers to more of my pedals.
Most buffers I've seen that use JFETs use J201s. As I understand it, JFETs are used because of their low output impedance. Since this is a property of most/all JFETs, does it matter which JFET I use? In other words, what are good alternatives to J201s, and why? I'm not nearly as familiar with JFET properties the way I am with BJTs, so I don't know how to evaluate what JFETs will work. Specifically I'm talking about the PPCB JFET buffer.
Thanks!
