Hi there folks!
Here's my tries at etching... damn it's hard.

I can't how some people manage to do those super clean etches.
My third was a complete disaster..

But the last one turned out good, finally!
I've had no luck with ferrit cloride. Tried Cautic Soda on the last one.
Followed the tutorial by DIY guitar effects and it turned out much better.

The Caustic Soda seemed to not eat away the toner as fast.

Cheers
