Hey friends,

After I've built glitterratti, I tried to built Boneyard "Modified"  (Carl martin Plexitone as listed in http://www.madbeanpedals.com/projects/Boneyard/docs/Boneyard.pdf) and It was great sound. I followed all the Boneyard.pdf, including 47 Ohms Resistor value, 151pF,etc.

I have a quick question, that some of MB members have faced down, pretty sure, I also on the same boat with them, but mine, quite weird.

The Problem
I came up with ICL 7660 for the IC2 and LF347 for the IC1, seems ICL 7660 works for this project, but I got a whine sound or some of members here called oscillation when I turned up the tone pot from my Guitar, about 50 to 100 percent of tone, then I tried to lower it down, and turned up my guitar volume to full knob, I still got the whine, and also when I turned down the guitar volume until 50%.

My thoughts about this issue
After several discussion with my close friend who have been built some several pedals, he said first try is to give the INPUT and OUTPUT jack a shielded cable, so it will reduce hi-gain frequency.

If it's not give any differences, so I tried to put 1K resistor near between INPUT lug and GROUND lug at ON/OFF 3PDT

My friend also told to me lower the caps value from the ICL7660 or change into MAX1044 (as it mentioned in pdf)

My questions
1) Will the shielded cable kill the whine / oscillation of my boneyard ? If it does, then I will do it
2) What should I do to kill the whine problem between my boneyard and guitar volume/tone problem ?
3) Will Boneyard wipe the whine if I change the ICL7660 into MAX1044 ?
4) Do you have some other ideas not listed here? Please tell me

Thank you

First of all, I tried to make this clear, I feel very sad right now because I didn't make it sound right with my gliterratti....  :-\  :-\  :-\

I follow the steps from 3.5 version. I believe I'm good at electronic soldering, but I've still do not have any idea what happened with my glitterratti..

I want to cry right now, because I haven't idea to do with it. I checked wiring, what I've found the IN pin connected with Ground, it just a simple clue, but I still do not how to fix it, so please help....

My first assumption is I've got wrong in soldering the switch, because the LED turned on but what I've heard was a buzzing everywhere and I don't get my true bypass...

My glitterrattii is still naked-unboxed and I believe I should have the bypass when it turned off, but I haven't.

I just got buzzing and noise sound everywhere, I couldn't here my guitar sound...

So, Please help me to solve this problem...I'm really frustrated here....I really appreciate with your help and experiences....

----------------------------
Assumptions:
1) bad wiring in 3 pdt, I don't know how to, please help
2) bad wiring joins....I will upload the pictures tomorrow (I believe I have fixed my wiring)
3) I still use the part as mentioned in 3.5 Glitterratti version, I soldered the pots in the right direction (3-2-1), but I believe that I missed a point, but I don't know....
4)..etc

Regards,
