I have a little ongoing offline dispute with a friend who says that Boss pedals do not affect the tone of the guitar signal when they are not on (bypassed). I disagree, on the premise that Boss pedals (specifically the DD-20 Gigadelay) are not true-bypass. It is my understanding that the tone is affected no matter what with a pedal that is not true bypass. All you tone experts out there, what is the truth of the matter? I'm willing to concede this friend is correct, if it does turn out to be the case, but this is my current understanding. Anyone?
