3 questions guys. 1 - Other than looking at the manual for the specs, is there any other way to determine input and output impedances of buffered or true bypass pedals that are turned on? 2 - I read somewhere (maybe here?) as a 'general' rule, the input impedance should be at least 10x more as the output impedance of the pedal before it to play 'well' together. As in from 10k (or less) output into 1m input. Is this generally true? 3 - Is a buffered pedal with 500k input impedance considered a low input impedance? As in it loads the guitar like fuzz faces do? If it is, this is bad for my signal as the buffer's always on, no? And please save the "If it sounds good to you, why does it matter?" talk. This is for my own knowledge. Thank you!
