My phase 90 clone isn't working

And heres what the top of the board looks like

Hope you will include a warranty on this.

This things has more shorts than an Old Navy in mid summer.

I'll see myself out. Best of luck, Snow. Go back and read what Tom was explaining.

its kinda behaving like a super fuzz now

Me too.  Unless and until you accept and follow the good advice given -- and abandon your haphazard approach -- you have no hope of getting anywhere.  A bunch of monkeys with typewriters may indeed eventually write Hamlet, but none of us will live that long.

What is it called when you do the same thing over and over expecting different results?

debugging.

just as long as it doesn't start behaving like a green russian big muff.

well im trying to fix the shorts, and if i cant find any with a multimeter or anything i give up on that part, then i look at the board and see if anything is missing or isnt soldered, then i look at the schematic and see where the signal went wrong and then see if swapping a component out would work.

[snow123]

and there arent any shorts according to my multimeter, and idk if i cant trust it at this point tbh.

[antonis]

and there arent any shorts according to my multimeter,

If so, trust your multimeter and PLEASE let us rest in peace..!!

ok, theres no shorts.

[antonis]

ok, theres no shorts.

[snow123]

yea im sure there arent any shorts anywhere,

[snow123]

ok i just replaced the 47uf cap and that fixed the weird flubbery super fuzz type sounds i was getting, now its just a dry signal when its turned on.

[ElectricDruid]

so now i do have a phaser effect, but not the big swooshy phase 90 effect, y'know?

So what happened since this point? It sounded like you were pretty close to having it done, but you seem to have gone backwards. What have you done? Did you fix that short and the missing resistor that Antonis mentioned?

My advice is to *not* change anything unless you've clearly identified it as a problem. Debugging depends on having a known situation, and if you randomly change stuff, you don't have that. You don't know if the problems are in the original circuit or introduced by the changes you made.

Do an audio check through the circuit like we discussed earlier on. Check the output of the input buffer and the phase stages. Make sure you've got clean audio at all those points.

i was trying to identify and fix a bunch of potential shorts but i think i overheated the 47uf filter cap while doing that which resulted in that weird flubbery super fuzz thing, so i replaced that cap and that fixed the issue. and i did fix that missing resistor.

[snow123]

This is the only short in the circuit but I don't know how to fix it

[snow123]

and im not getting an input signal now.

[snow123]

i just realized that short was toggled with the footswitch. i guess i cant confirm that there are 0 shorts now LMAO

This thread is very entertaining!

Why do you put so much solder? Perhaps you're using a solder wire that's too thick? And that makes it hard for you to control the amount?

I recommend using thin solder wire. I find 0.5mm to be perfect. Thin solder wire will make it much easier for you to control the amount of solder that goes on the pads.
