Slow Attack Swell NG-100 tracing help

[lars-musik]

Hi there,

I frequently whined about my problems that I can't find  a suitable auto-swell circuit. I tried the Slow Gear, the Gator and even had my tough time with an EHX Attack/Decay.

Unfortunately I found a solution for 24.99 EUR at Thomann: the Harley Benton NG-100.

But for several reasons (foremost vanity, I guess) I want it in a DIY Version. So I tried my first pedal trace on this circuit. Now, I came up with a schematic (my first, so please be polite) but I guess it is hard to read and most certainly flawed in one or more ways.

So I would kindly ask for your help in converting this schematic into something legible and buildable, especially regarding a true bypass conversion (which parts are superfluous?) and probable errors I made tracing the pcb.

To those willing to help I'll gladly send the diptrace files.

Thanks very much in advance!

Cheers, Lars

I'll look, if you can export to jpg or png big enuff so I can see (I have eagle, no diptrace).

Following this. Cant read it, and at this stage I'm not sure i'd be able to help but you never know.

Oh sorry, I thought the photobucket link would suffice.

Here is the schematic as pdf and png respectively.

If you need to refer to the pictures I took of the pcb you'll find a complete set in the photobucket library: http://s1244.photobucket.com/user/lars-musik/library/NG-10

I really hope you can help me with that because it sounds really good and would make a nice alternative to the Paia Gator. I traced it as close as possible to the original, even when things like the unconnected pin 6 of the CA3080 connecting to pin 1 gave me headaches. The lack of electronic background on my part however is mirrored in this schematic.

Hope to hear from you and many thanks in advance!
