I was reading this article by Pete Cornish (yea, the high end pedal builder whose pedals are way over priced) and he had a good argument about NOT using True Bypass pedals.
Basically, with "true bypass" pedals you run the risk of changing your tone with any on/off from a pedal in your chain due to the fact that it's a mix-match of input impedances that can vary greatly and basically no two pedals have the same input impedance. You've got pedals that have input impedance ranges from 1 Megohm all the way down to less than 100 Kilohms (less than 1/10 of the 1 megohm).
Does the Waldo preamp buffer help with this problem? Pete Cornish uses his own system to keep the tone: guitar into a high impedance load that is the same as the amp inputs', AND THEN a low impedance buffered feed to the effects chain - maintaining a constant signal level and tone that does not change when adding/subtracting effects.
This sounds a lot like the solution that was designed for Tigers signal path (other than coming back through the guitar). Was Jerry's tone changing all the time with Wolf and the Travis Beans after adding more and more pedals?
