ceramic caps tolerance (effect on meatheads and muffs)

[jtn191]

So my recent Meathead build sounds pretty great but seems a little noisier and quite a bit brighter than I expected. I double-checked the in/out cap values and they look legit. I think the culprit may be randomly selected Tayda ceramic caps, 20% tolerance. I heard most of these caps come up short of the marked value. Come to think of it, my all-ceramic muff seems pretty bright too.

My question: do you think these wide variations in the low pf range to have a big impact in the filtering on Meatheads and Muffs?

nm...I just doubled the input cap
