sea urchin pop issue solved. Now a clock noise on the background!

Hi guys

Need some help to kill the "pop" of my delay pedal!

i´m using a super bright blue led. does it matter? and 4.7k resistor


thx

Stick a 1M resistor from the output to ground.  Easiest way is to just put it across the tip of the output jack to the sleeve.

fx output?

[gtr2]

yes

you can use a 100k there and it works fine in my experience, in fact I think madbean is the one who originally suggested the lower value.  IIRC I used a 120k and I have no pop.

ditto 100k works for me in all iterations of the "deep blue delay" architecture that I have made

I solder it to the footswitch FWIW...

ok problem solved

The 100k works fine!  

now i hear some clock noise! not to loud but when mute the strings i can hear a noise like a clock. i´m supossing that the pt2399...

Another guess and doubt... i didnt use the footswitch wiring indicated by MB
I use a this key:


This key can affect the signal?

[gtr2]

Its the pt2399.  Some are louder than others when it happens.

Ok

Look can you explain the need of connect the fx in on to the empty center pole of my wiring key?

The bypass you indicated is fine, with one exception. What doesn't happen with that version is that when you are in bypass, the circuit still holds potential DC voltage. What we often do is 'ground' the input of the circuit just in bypass. So, to accomplish this, I would connect the upper left lug to the lower middle lug as well as everything else you've done. In fact, that's how I do my bypass every time I build.

The Madbean 3PDT scheme accomplishes exactly the same thing, but does it in a different way. If you want to understand it, or the bypass scheme you posted above, I highly recommend you read up on how switches work. I know Beavis Audio has a great Switch article.

thx for the explanation.

I found the Beavis article on switches, nice one btw, and i will add that extra connection.
