HI this is Walters

Ticking Problems
        1.) Dont plug your effect pedal or Amp into a Wall AC outlet if
       it has a DIMMER circuit.
        2.) Dimmers have Harmonics and Square wave output and
            spikes and surges sometimes can damage your power supply
       3.) it can not Filter out the High Freq in the power supply
       most power supplies are just to filter out low frequency not High

Use a Isolated Transformer for the Power and Audio ICs Seperate
so they are both Isolated from each other
its the Best way Because it Can REFLECT back into the circuit
and can be hard to trace because the ticking will come up through the
grounds very common.


I sometimes like to use Ticking sounds as an Effect
like have mulitple switches where ticking sounds can Reflect or bleed
through the Circuit from the LFO can be a special effect
for space rock music
if anyone knows any Ticking Mods i want more Ticking in my pedals
so Post me i like the ticking
what ever will make the pedal effect Tick the most really loud would
be cool thanks

that search button is a very good tool - it`ll help answering questions:

(a) dimmers don't cause ticking. They do cause buzz at the power line frequency.
(b)Dimmers creat harmonics, yes. They do not have square wave output. Go search the net for dimmers and phase control and find out why they do not have square wave outputs. Post back here what waveform they do have. Dimmers do not make spikes and surges. Go search the net and find out why. Post it back here.
(c)Tell me what parts of a power supply filter noise, and why they cannot filter out highs.

Nonsense. An insolated transformer may help, but is not necessary. I can't think of any example of audio equipment built this way.

Get off this "REFLECT" kick. Reflections are a time domain thing you can't see until you get well up into RF. It really has no application to audio electronics. If you think this is incorrect, tell us why.

So go get yourself a 555 timer and set it up for 1% duty cycle waveforms and get yourself a 0-to-9V tick that's fully controllable. Go search the web for how to do this and report it back here.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.
