Germanium Transistor Buffer

This is the board for the germanium transistor buffer board that is mentioned in the Guitar FX Blog. Each board purchase includes a free (leaky) AC128 that can be used to build the buffer. Printed instructions with parts placement, parts list and mods are included with every board.

Read more about this easy to build circuit.

[40] AMZ Jfet Buffer-Splitter

Date: August 26th, 2007 | Comments : [6] | Categories: DIY.

Guitar Pedal SplitterI was looking back at the jfet buffer presented earlier in this blog, and noted that it would be easy to add some extra transistors to the buffer to turn it into a multiple output signal splitter.

Also, the veroboard layout is easily extended to accomodate the extra components and I have included that in the article.

You can find it in the AMZ Lab Notebook.
