Sorry it took so long - but I finally had a chance to do some more testing on power draw. I plugged the AC adapter into the TrueTone meter and then cabled the meter to the Anagram. Tried it with a bass on the input and the output going to an amp. I didn't bother with a headphone test given the results below. I tried a number of different anagram patches - some with 8 blocks, so a good test of CPU usage and the results didn't change.I have one of the TrueTone current meters - where you plug it into series between the power supply and the pedal and it will tell you how much "actual" current the pedal is drawing. My plan is to use a Cioks SOL and the "three slot" approach as many have mentioned.
Using the power supply that came with my Anagram - plugging that into the TrueTone current meter and from there into the Anagram, I only saw current draws of less than 1A from the Anagram. It fluctuated a good bit from ~700 to 875 mA. To be clear, I didn't plug a bass in and play through it to see the current draw change (which I will in the next day or so) - but it's clearly drawing way less than 2A. I can't imagine that the current draw would increase too significantly - but will report back what I find.
That little test made me very confident that my Cioks SOL could handle the Anagram, and Strobostomp HD, and my Cali76 V2.
Basically, I've come to the conclusion that while the TrueTone meter is supposed to show "---" if the current draw is above 1A, I what I'm seeing with a constant fluctuation of current draw between 585mA and like 872mA is an erroneous reading. I testing the meter with a variety of other pedals and it holds constant - so the weird fluctuation when testing with the Anagram makes me think I'm not getting a true reading. I'm suspicious that it's drawing more than 1A and the meter is doing what it is as a result of that.
Having said all of that - I'm still quite confident that the SOL will be fine using 3 outlets. They max at 660mA per outlet - so paralleled that gets me to 1980mA and given that the Anagram is "rated" at 2000mA draw, and those ratings are always pretty conservative - I think it will be fine. YMMV.
I freakin love this pedal. So intuitive and the sounds are really flexible for my needs.
