Thanks for your input. I already thought of that one. I wanted something a little more versatile. I can’t think of any other way to do it, unfortunately. I don’t know if the symmetrical/asymmetrical switching does much anyway, since to my ears most dirt is dirt. I must have at least 20-30 dirt pedals and listening and comparing one to another (which I have done in the past) there doesn’t seem to be a lot of difference, except maybe for some of the more crazier fuzz sounds. But when it come to OD and Distortion pedals, there doesn’t seem to be a whole lot of difference to me when it comes to the basic dirt of the pedal, although the different circuits tend to color the sound in different ways.
