Hey all,

As the title says, I finished the Freekout, and when engaged, I'm getting a boosted signal but no modulation. I can hear the whine of the generator, and it goes up and down if I adjust the pots, but no effected signal.

Checked all the part values, I don't see any solder bridges, here's the voltages:

Input 18.06V

General Questions / Odd Current Lover output issue
« on: December 24, 2019, 12:06:43 PM »
Hello,

Finished the Current Lover recently. Worked great unboxed. After I boxed it, the effected part of the signal went away. So just clean signal with the effect engaged. After some messing around, I discovered that there is some issue with the in/out jacks. The problem is happening when the jacks are installed in the box. If i unscrew them and hang them off the side of the box, the effect comes back. I've tried different jacks. This enclosure is unpainted. Am I grounding/shorting the board with the jacks touching the metal? It doesn't seem to make a lot of sense. I thought about trying to cover/paint the inner edges of the holes for the jacks, but what would I use? Thanks!

General Questions / Current Lover question
« on: November 29, 2019, 01:35:37 PM »
Loved building this, and it actually worked the first time I plugged it in!

Question: as I am adjusting bias, around the mid-point there's a ton of distortion. Is this normal? I have to set the bias trim to 100% to get flange, and it's still kinda noisy. Is there a chip i should try swapping out to see if that makes a difference? I bought my BBD from Small Bear, so should be legit.

If anyone has any tips, let me know.

Thanks!
