I see that Ernie Ball has realeased a smaller set of volume pedals called Jr. Volume. There are 2 models and active model with a 25K range and a passive model with a 250K range. The question I have is which model works better for bass. My basses are "active" (Stringray and Wal) so would that imply that I need the "active" pedal or would the "passive" one work? I like the idea of the Jr pedals because they seem to be smaller and cheaper. Any thoughts?
