Here is the “Screaming Duo” – two Ultra Tube Screamers run in series with an Easy Order Switching Board (Toggle) between.
For the 1st circuit I went with the stock LDO build and the 2nd circuit I went with the RTO version. For both versions, I used an on/off/on toggle for clipping selection and a toggle at D2 to allow for switching between symmetric and asymmetric clipping when using the silicon clipping option.
If you like Tube Screamers, you will love the Ultra and if 1 tube screamer is good then 2 has got to be better!
This one is in GuitarPCB Orange.
Enjoy.
