I'm building a neutron and it talks about connecting an 'input stereo lug' to take advantage of the stereo jack trick. If I'm not using a battery supply but a dc 9v wall wart do I need to hook up this 'input stereo lug'( I feel like the stereo jack trick is advantageous if your using batteries)? Same question (do I need to hook it up) about the "Dual Voltage Supply Connection' rectangle on the schematic. I'm thinking that one is a more obvious 'no' answer but I'd feel a lot better hearing confirmation from you guys. Thanks.
It is not necessary if you're going to power it using a power supply. In fact, I once had a big muff that had a toggle switch on the top to turn the effect power on or off, it didn't use the input jack trick.
Thanks for the help Ed
