I just confirmed with True Tone that their CS7 will power the H90. Even though the highest current output is listed as 500ma, the total current load can be up to 1900ma which is automatically distributed as needed, as long as the total draw doesn’t exceed that total current number. Given that my other pedals draw about 200ma, I have a fair amount of headroom.
I tried this today, It powered up, but a very loud hum.
Does anyone have any idea what the hum is from?
Works great with no hum with the wall wart it came with.
