On one version of this page, the pot value for the dying battery simulating mod is 10KB; on another, it's 100KB. Which one is more suited to this task?
I should think that a 10K should be more than enough, but then again, I suppose that it depends on the circuit and voltage. On my pedals, I range between a 5K, down to a 2K. All depends when the circuit dies completely.
