Ralf's Single Channel
Our good friend Ralf (http://www.ralfschreiber.com/) has shown us his nice new workshop module for making a single channel piezo pre-amp during HOME MADE 2020.
Some discussion on how to use a linear pot that reacts logarithmically by adding / chaning one of the resistors?

Extra Puffer for Batterie and DC-Power supplier
> bei batteriebetrieb noch 100uF-470uF elko als puffer,
> bei netzteilbetrieb mindesten ein rc glied R10/220uf dazu!
Other Op-Amps for lower supply Voltages
MCP6002, MCP602, TLC272, LMV358, TLV9002
