thatās different than hum - the distortion point will change with the loudness of the guitar output. That one I can see being of interest if you can control your playing to be at the cusp of the sag.
Mains hum can influence fuzz as it adds a 50/60 cycle tone into a non-linear device which will give interesting multiplications of that 50/60 Hz into the effect. Iād be more likely to call it noise, since it is off from a normal note frequency, but artistry is hard to argue.
All my pedals are 9V. This is the little bit of magic underneath:

It was actually made for a pedal board power supply, to convert an unused 18V output down to 9V.
Mostly, but also portability. I am playing with headphones, so I can pick this up and go anywhere.
I havenāt tested that yet, but I have a range of 3Ah, 4Ah and 5Ah batteries, so can always bump up the capacity if I need to. The other thing I like about Makita batteries is they have a built in battery level indicator.
Besides which the hammer action helps with the Metallica rhythm playing right?
I use a Donner isolated power supply that cost $40 US. A Makita powered board sounds far more industrious though. 
Awesome. Good on you!
Itās actually incredibly quiet. My main pedal board that goes into the small Vox amp has a bit of background noise when you arenāt touching the strings. It can also build up some static noise from the pickguard when you are strumming. This has none of that.
I have been playing it for 5-6 hours now and the battery level indicator is still showing as fully charged.
Also I realised an added benefit. We have been having thunderstorms the past few afternoons. No need to unplug anythingā¦ I can just keep playing.
I made this as a travel pedal board but I think it will be getting a lot of use at home too.
Itās a great solution. Especially as it makes use of battery packs you already have.
For anyone interested in this who doesnāt have this sort of battery pack, or who doesnāt want to DIY it, thereās some pedal board power supplies with built in rechargeable batteries:

Genius Alan!
For anyone wanting to try this I have an update. The Truetone 18V to 9V converter I used is very limited. I tried adding one more pedal and it started getting seriously hot. I eventually managed to dig out the specs and found it is rated at max 100mA current, which is actually below most modern pedals.
I will be swapping it out for this DC to DC step down converter from Jaycar (max current 1.5A).
