About a week ago, I got an email from a friend of a friend, with a couple of ideas for new pedals. The first, less exciting one, was an standard A/B looper, but where, instead of a switch to change between A and B, the switch would be used to swap the order, so you could have A running into B, or B running into A. This seemed like quite a cool idea, and with not much searching, I found a schematic for it over at Beavis Audio, job done.
The next idea was more exciting. Another A/B Looper, but one where the loops are turned on and off alternately via a tremolo type circuit, and with the possible option of an expression pedal to replace the tremolo. This one's still only partially made on the breadboard, but I have got 2 LEDs flashing alternately, with rate, depth and speed controls, so it's all looking good!
