Buffers

Following a couple of threads in the forum where people had oscillation problems with certain effects that disappeared when a buffered pedal was placed before them, I said I'd do a post on here with a few different compact buffers that people could try tucked away in the box to place in series before the effect board.

So we have:
IC vero using TL071
IC perf using TL071
JFET basic buffer
JFET buffer with voltage divider for increased headroom.

Looking at the differences in sizes I'd be tempted to try the basic JFET buffer first, because if that does the job well enough it's so small that it should be easy to fit in any effect's box with the minimum fuss.
