Hi, A few days back I was about to buy a ABY Switch from Robert Keeley and then I felt I could make my own as I had prior experience in making similar switches. I told Keeley about my idea and he was impressed. So I decided to do my own. So I made my own circuit and made a 100% true hard-wired bypass ABY Switch. It's working fine and there is no noise at all. The difficulty is now fitting them inside a stomp-box. Hopefully it will be done in a few days and I will post the picture. Now this switch will be really useful in a lot of things. 1. I have a pedal board and also a processor. Now with the AB switch, I can switch between these two without having to use the processor's lousy bypass. 2. I can connect my rig to two different speakers and change them as and when I want them. 3. Two different guitars connected to different pedals can be connected to the same amp. When I have to change the setup, I can just stomp and change my connection. 4. Lets say, I am playing clean with chorus one and now it I have to immediately go on a distortion solo, which requires me to switch on the distortion pedal and clean boost pedal plus switching off the chorus pedal. This requires three switching in a short time. With the ABY switch, I can do it one shot with just one button press. So all you guys who complain about Tap Dancing with stompbox pedals, ABY will be a cool alternative. Next project is my clean boost or a treble booster. Will post details later.
