ok, no worries, ive stripped back the layout  back to basic without the ground pour just to see it easier...

have fun!.. ;)

i'll get as much done before i test my home brew beer thats ready today!!!...hair of the dog etc... :P


ive audio probed this, getting 'tremolo' at D1 right side!
and audio at pin3 mn3007....dirty, and no chorus..

I understand if you feel a bit tired after running from your queen this weekend, it doesn't look like she likes people running away from the celebrations...

Also Rob...

Is this a typo? Why do you have a fluctuating voltage on the COLLECTOR of Q1 when it is supposed to be tied to GND?  ???

The transistor isn't installed backwards is it?

Yes it is however, the Collector of Q1 is tied to GND. You posted it as having a fluctuating voltage.

You definitely have an issue around Pin 2 and 3 of your TL072. Thats where you signal enters the circuit  :-\

Bad IC perhaps??

OK.... so like my avatar Patrick says: "Only clean output!!"  :icon_lol:

Probably a bad 4558. You could try another but, it really should not make a difference.

Might want to repost fresh voltages  ;D

Any difference in the output with trimmer adjustments?

Dodgy 3007?

no diffeence on out at all with trim adjust... ???

i stuck a 100pf instead of 150pf going to the 4047...shouldn't matter though?..and a 47n on  input instead of 33nf


edit: if i stick an audio probe on D1 or pin 3 of 4047 and adjust trim i get distorted semi warble sound.....
