Im gonna try my first attempt at a delay pedal, & just picked this one, based off this schematic, adding the charge pump to run off 9v.  Hoping someone could review & give me a heads up if I made anymistakes, or things to look for when I go to build.  Laid this out for point to point on a perfboard (yes I'm cheap & works for me).  I use a number system for wire connections.  Not perfectly to scale, part sizes are based on what I have on hand.  Thanks in advance for any help.

I'd say this circuit will eat too much to be powered by 9V battery (even the Vref divider by itself eats more than some pedals /6mA/, it's obvious, that it was designed as wall wart powered effect).
Do you have a technical question? Please don't send private messages, use the FORUM!

I can try it, if it dont work out, I should be able to  take out the charge pump  & battery connector & convert it to use a walwart, & not  affect the rest of the circuit.  Thanks for the heads up though!
