Looking at the Fender Layout https://cdn.shopify.com/s/files/1/2325/2729/files/Princeton-6G2-Layout.pdf?5926397210715640943 and examples I have found online the Speaker out and Aux speaker out are two differrent kinds of plugs. One is a Switchcraft 12A style and the other is a Switchcraft 11 style. It's my understanding that the 12A style has a grounding shunt that is deactivated when a 1/4 plug is inserted and that is there to pull the tip to ground when nothing is plugged in to that jack and help with noise on the empty jack. If that is the case then why is it that in the Fender layout diagram and most of the examples I have found have the Shunted jack (12A) on the Speaker plug and the bare shuntless version (11) on the Aux speaker plug? This leaves the mostly empty (unless and external cab is being used) plug shuntless and open to noise. It seems it should be the other way around, or even better a 12A shunted jack on both. Am I missing something?
