Hi,
I'm new here and for the most part suck at this stuff, but keep going for some reason.
I'm trying to build this circuit for a pal (he needs to raise his 'woody' humbucking acoustic guitar pickup to line level and could use some tone controls, too):

i used a LM741 instead of the 709, which i read in the datasheet is a direct replacement. i wired it with 9v and 15v. Dbl checked the wiring. ...nada
I am getting "-.25" volts at the output of the opamp.
anybody know what might be going on or what to check next?
