[SOLVED] Lectric Fx Flintlock Flanger kit sounds very dark

[eh là bas ma]

Hello,

I built a flintlock flanger some time ago, unfortunatly the signal gets very dark when I engage the effect, even when I remove the modulation by setting Threshold fully CCW, and Manual fully CW.

I tried to fix it myself without success by tweaking Mix and Bias trimpots.

On my build the sweep is set between 73 KHz and 2.2 MHz, to avoid distortions at both ends of the sweep.

In order to bias the clock frequencies, C-Range internal trimpot is set fully CW, and Auto is set fully CCW.

The volume internal trimpot is set fully CW to get the same level of volume when the effect is engaged.

I do have 15V at test point near IC11.

C37 is empty.

I did a recording so that you can hear what I mean by "dark" :

Any help would be welcome, I love this flanger and I have no idea how to fix it...

Edit : I think I managed to fix it by changing the 2n5457's orientation (opposite from the pcb silkscreen).

I also added the modification I found here : https://www.madbeanpedals.com/forum/index.php?topic=31768.0
