Result
Italian V846 ICAR has the steepest curve. It has no sensing zone at first and then goes up radically.From 80 % of the resistance, it goes gradually to 100 %. Hot Potz-1 does not have "No sensing zone", it goes gradually up from the first So, it's difficult for us to control the most usable lower zone. It goes over the most usable point at the first. Fulltone pot is closest to ICAR pot. It has some "No sensing zone" and steeper than other replica pots.
