*PEDALS PEDALS TO BE AWARE OF WHEN COMBINING POWER*
Transistor-Based Fuzz & Octave
Digital Pedal (including Tuners)
*Note, this is not a die-hard rule, there are many exceptions. This is a good place to start. It's always best to test for yourself and see if you get added noise when powering pedals off of the same output. You can test this easily by unplugging power from one pedal and see if the noise lessens.
