Can anyone explain why the best ones seem to use germanium transtors, (
and 'matched pairs' at that)? Why not a simple op amp with back to back

They were named for a co-worker, Frank Ryder, who was also a small

sick was after an hour flying with him.

The Ryder amp had a path that used a tracking diode clipper followed
by a diferentiator. They called it "bell tone", not fuzz. It had a
"long sustain", whatever that means.

Low damping, so the tone dies away slowly.
