Ionosphere issues

[DGWVI]

So, I've got this built up, bypass works perfectly, but the circuit itself seems to be acting like an lfo/ tremolo- no fuzz. Any ideas?

I've triple checked values, reflowed the solder, and tried several op amps to no avail

based on the circuit diagram in the build document, nothing should be giving you any kind of vibe/trem behavior unless you have a spotty connection in your audio signal path.

What kind of sound your are getting through the PCB compared to your bypassed signal? At least as loud as the bypass?

How loud above the bypass signal can you go using the volume control when the gain is turned down?

What happens when you rotate the gain control? Any change in volume or sound?

Is the tone control working? Does it do anything unexpected to the sound? (big volume drop, makes dogs bark, changes channels on the TV...)

While you are at it, go ahead and quadruple check to make sure R5 is the right value (1 Meg), since that sets the high gain the circuit is supposed to have.

The circuit only reaches unity gain. Sounds basically like the clean tone, except the tone and volume do effect it. The distortion pot adds a subtle background fizz as it's increased. R5 is indeed 1M

check your voltages in the circuit on IC pins 3 and 5.

you should put together an audio probe and start investigating the sound levels through the audio path. check out the other help requests on this site and use google to see how to put together a probe using an audio cable, capacitor, and a clip.

Thanks for the help, but it turns out the stomp switch was faulty. Swapped that for another 3pdt, and it works as intended
