You can always run it on 18V.I didn't have room for the charge pump
You're right, but I think that might have tipped me past my area allowance in Eagle, the free version is not overly generous! I’m trying to migrate over to KiCAD, so that should mean I can have as much space as I’d like, but I’m not finding the transition as easy as I though I would.
For this circuit I like it at 9V.
I’ve just ordered some bread boarding bits and pieces so hope to play around with some circuits over Christmas.

I once made one of those in pursuit of the Marshall tone. I just looked, it was 15 years ago. I made a second one for my friend, and for a while we thought it was the bees knees, but then we got bored with it. Maybe this is some kind of listening fatigue.
Back then, I noticed that the reference voltage varies considerably with the amount of voltage dumped into it upon distortion peaks.
I made an attempt to alleviate this as good as I could. This was at a time when I did not know all the stomp box trickery yet.
I have noticed that the guys who design those circuits, particularly if it is just a re-hash of some predecessor, either do not know their business very well, or are entirely buck-driven on some decisions.
But later I was not so sure about that. Maybe they were genius...
So technically, I totally agree with a proper ground lane and symmetric supplies, such as Chuck has suggested it. But again, it may have some musical effect. The low time constant this filtering has until it recovers. This reminds me of the trick R.O.G. played with their Thunderbird unit.
These days, there are better Marshall emulators IMHO, such as the aforementioned unit. Yet somebody may sound great using this unit. It is like an ugly color that may look perfect in the hands of an artist. (Not saying the KoT is ugly...)

With this circuit, I was not going for a Marshall tone, or any other amp for that matter. I was going for a pair of stacked low-medium gain ODs where the dynamics and distortion are easily tailored.
