Acoustic preamp schematics: any experience ?

[Schertler]

Hi,

I was looking for acoustic preamp schematics and found that there are some circuits available from the manufacturers, I mean they should be correct for building some DIY devices ........

Does anyone tried these ones from Fender or SWR ???
