Hi guys.
Yesterday i've built Princess Rawr PCB by Rullywow, which is Catalinbread Katzenkonig thingy . And overall it sounds very good, but the hiss is kinda annoying. Transistors are 2n3904 around 360 HFE. The most hiss I get is from Gain Knob.

Here is what I tried to do:
1. Decreased R5 from 10 k to 1 k. Was kinda helpfull to decrease hiss for the input knob.
2. Omited R8 (150Ohm)


After that i've installed a 20k trimpot instead of R10, and got quite nice sounding gated effect with no hiss by cranking gain knob. But using lower gain it still goes hissing.

So, maybe someone, has built it without these noise issues?

Best Regards,
Ivan

Hi. I've tried to build the Aion Solaris PCB. But, after trying the pcb the signal goes oscillating. And sound is quite noticeable about 10kHZ freq.
The IC Pump is ICL7660 with frequency boost feature, but it doesn't seem gets engaging. Tried to mess with the caps, but it doesn't get better.
Is there any way to eliminate that noise?

Hello.
Here is my build of Brian's dirtbaby delay.
The wiring on this board is awesome, and overall sound is so spacey especially with the modulation on.
I feel kinda shy about the gut, but it sound good

Also this one is a runt - my fav overall gain pedal by now.
