Analogman buffer schematic?

Anyone has it? Would like to know what are the extras to a common buffer. Tks!

Never heard of that buffer, google does not seem to know any schematics for it either.
From what I have been seeing, "aclaimed" buffers are usually just textbook circuits. There is really not much to them. All they are supposed to do is provide a high impedance input and low impedance output, while passing the signal.

A regular opamp buffer will do that fine (Ex Klon buffer). Not sure if there are any benefits of going into anything fancier.

Honestly, the analogman web site tells you exactly what they do: Tube Screamer-style transistor input buffer into a 4558 op amp output buffer.  Between that and the information on the AMZ buffer site, you should be able to recreate a reasonable facsimile.  Bonus points if you can read the resistor color codes in the photos.

There is a Cornish buffer that Brian posted in the extra projects page if that helps

this its the dual buffer i talked about, its really simple and common buffer, has no extras, and works like hell

Thanks Copachino for posting that. Here is one I am working on that I still need to test. I hope to get this tested this week in a Ernie Ball VP Jr I am working on.
