carbon zinc is best, many fuzzfaces sound kinda ratty on an alkaline or a 9v supply
some builders solve these issues in the build and I have had some that sounded good on a power supply, but often the battery rules with the basic ff circuit.
as for why it works best, I am no materials scientist, but I suspect they were designed with this power source, alkaline wasn't available for sale in the sixties
So is there any truth that fuzz faces sound 'better' (fuzzier?) on carbon zinc than they do on alkaline batteries? Or is it a myth? And if the consensus is that carbon zinc works better, why would that be the case?
I haven't noticed a bit of difference in my FF Hendrix mini between carbon zinc, power supply, or alkaline. Zero.
