18V Klon (No Charge Pump) Variant?

I just did this. It’s almost minor but makes the difference. I also swapped the volume for a B10K and the gain for C-taper and it’s much more usable.

Nice, it's just enough of a changed to make it worth using.

Totally agree. I put it on a clipping switch but it’s a waste of a SPDT! LED all the way! (And they light up a little which raises interesting enclosure art possibilities)

Looking forward to my Skeleklone build after discovering my VIIb picks up the charge pump whine from my current kliche, just like my Old Chap

Sorry if this is mentioned above, but has anyone tried isolating the OUT ground? If the input and output cable grounds are tied to the klon circuit ground, they’ll be DC coupled to the circuit ground of the following circuit(s).

If I’m understanding you right, without grounding the output, you wouldn’t have anything but hum. I’m not sure to what else you could ground it any other way.

Good point, I should've suggested better isolation of the power and signal ground. That's a design issue and is not a simple fix that can be implemented on a existing board though.

brilliant reference, targeted towards tube amps, but still relevant concepts to pedal circuits
