    My 18v high speed preamp in my Adler 12-string bass was installed in my bass over 15 months ago.Two 9v Duracell batteries were used.I am still using the same two batteries 15 months later,with a minimum of 4 hours a day of use.That seems like a long time for batteries to last drawing 18v. It must be those expensive chips.
    Anyone experience something like this?
