| br>I've built a couple of these and noticed that there is a higher noise-floor from the state outputs (on both channels) when the state pot is turned to the low-pass side (CCW).
When the pot is turned to the high-pass side, the noise is reduced. Even when the filter is fully closed (freq pot at min), you can still hear the noise.
All the other outputs are fine.
Can anyone confirm that this is normal behaviour and if there's a fix? br> br>
