Shaka Express Help...

[coxter]

Hi I've bought all the parts to build the shaka express pedal featured on the site.

Pardon my noob/ignorant questtion but, I dont know where the output portion of the circuit is...

And on the layout designed by Aron, theres 2 C13s, one on top of R7 and another one between the vol and tone pot.
can someone help me out ?

It seems like C13 and C14 on the layout should be C14 and C15.


The Output is at R21 pin 2

I use both the Schematics and the layout as references for building, but it seems at certain junctures/segments, niether of them tally up with each other.

So whats the value of C14 and 15? Because I can't find C14 or 15 anywhere on the schematics. and also... the Op-amps specified on the schematics is RC4558 but the one on the layout is TL072, I stucked with the TL072 anyway, just wondering if it matters. BTW, Is it okay if I used 1/4 or 1/2 watts resistors for this project?

Last question, I used a 9V battery for the circuit, and the schematic says 18Vs is required. and there was this tiny segment of the voltage doubler circuit. Assuming it works. is it part of the Layout drawn by Aron already ?

Thanks alot Gilles,
