wait till I have some spare change and I'll send you a board I made, while I was still learning... (actualy I made two, but one went into an amp...) the bottom is not pretty as it was handdrawn, but it funtions 100%, all you need to do is put chips in the sockets and solder in some bypass cap (I reused the little 10nf wimas that was on there in something else).

Drop me a mail with your address..

Please visit my friend's site for a bunch of effects circuits....

Casio, you would need to contact me useing the e-mail button below my post... as I am not sure this forum allows us to communicate about small transactions like this.

the PCB look differ from the schematic , with calcualting the resistors in the schematic , there are 38 Re's , the PCB has 36 Re's .
so whats wrong with that circuit

I did a test and the sound very bad .
Thanks

I see you were looking at a diffirent project.. I have the p88

I guess those extras may be the optional resistors/can be replaced with wire links, similar to cmoy layout.. its just a guess though.

You need to be more specific when asking for help. Help on PCB design is not clear, what is it that you want, you ave any design for which you are seeking help, or you want to make your own pcb via toner transfer, fabrication, silk screening or anything.
I am not trying to throw flames, just helping you to be more specific in your posts.
