I use mine with a GigRig I picked up second hand for cheap. Gives me IEC and plenty of ma.
Outside of that I generally power it via usb c with whatever I’m using for my iPad and have nearby. Any battery that will do PD (Power Delivery) will power it, just need to specifically look for that PD output.
I’ve just ordered the Darkglass Midi switch after some friends gifted me a Thomann Voucher for Christmas so excited to incorporate that. Mostly so it can sit on my desk so I can fiddle with it but then still turn stuff on and off when playing or even be as bold as to use the looper.
The Mood fuzz is great, very quick and easy to dial in an hitting a tone I’ve been using a Subdecay Noise Theory nam for.
I wish I had something more intelligent or articulate to offer but the Anagram is just doing everything I need, I’ve gigged it twice, run it as an iem mixer and all my fx, since I got my Punchline nam into it, it’s been perfect.
Might even be listing the last of my pedals for sale soon.
