I wanted to try a 2 way switch to extend my switch options. I found a 3 way switch I didn't use anymore and decided to try this before buying a new boss stereo switch. This works perfect! Switch A delay on/off, switch B reverb on/off and switch C delay+reverb on/off. Off course you can choose other combinations but the C switch is a bonus. Think of 1 switch to put boost+delay on for solo playing. Anyway, thought this might be interesting......
