Did you use shielded wire to connect the controls and jacks?
Thanks for your reply...
No, just normal stranded wire. Is that where the most interference
would be leaking in?
I found shielding paint (see below) - would it help to paint the
inside of the project box with this?

For $24.95 plus shipping, that's some mighty expensive shielding. Why not spend
about half of that and buy a proper aluminum chassis for it. They offer
inherent shielding. You'll have to do a bit of easy drilling to mount the
components, but it's well worth the effort, and it looks so much better than a
cardboard box.
Surf over to
www.mouser.com and search for Bud mini-box. There are quite a
number of sizes available; one is sure to fit your needs.
Cheers!!
