first post here, but i have been around for a while.
Recently i finished my first project (a JH fuzz facehttp://www.montagar.com/~patj/jhfface.gif) housed in a wooden box.
I build it straigt away without any testing and the result was really good with a problem of a little noise when the effect was active (a constant zzzzzzzzzzzzzzzzz, is this what we call hum?).
Unlikely i do not have any equipment (multimeter etc) to carefully chech what's going on and my only debugging tool is a led to check the solder joints.
The circuit is soldered on a simple prefboard (not the one with premade lines) using an old cheapo soldering iron and bad quality solder (the floor of my room was full of hundred mini solder balls ).
After finishing the project i learned that building in wooden enclosures creates a lot of grounding problems, so i added a small aluminium film which i connected with the circuit grounding. I also put a piece of cloth under the circuit so that solderjoints do not touch the wooden bottom. However the noise is still there.
So i want to ask opinions about what should i look for next.
1-Should i resolder the whole circuit?
2-Should i cover the whole box with metal film and connect it with the jacks grounding?
What i have noticed it that when the circuit is outside the box (hanging on the air) the noise dissapears. When i touch the circuit (joints or jacks) the noise comes back.
I know that maybe my question is really noobish and the information provided very little, but if you have any ideas that could help me find out what's going on, i would really appreciate it.
Thanks in advance
