Just grabbed a Katana 50. Killer amp especially for the price. The update back in October expanded the presets from two to four by adding bank switching. I know this is the Boss pedal recommended for switching channels and banks. https://www.roland.com/global/products/fs-6/ Can this or any two button latching switch with a TRS plug be used as well? Like this? https://www.long-mcquade.com/1771/Guitars/Parts/Apex_Electronics/Two_Button_Footswitch.htm The Boss pedal is $60.00 and uses a 9v battery that users are saying doesn't last long and requires unplugging when not using. So if the Apex or like pedals work it could save money and inconvenience.
