This build houses two Xotic BB Preamp clones in the same enclosure with one foot switch that bypasses the entire pedal and another foot switch which toggles between the sides. I use it to set one side for a slight breakup and the other side set for a more aggressive tone. Switching between sides doesn’t drastically change your tone.
This was my first build using an Aion PCB. I was impressed by the quality of the PCB, the quality of the build doc and by the accuracy of the circuit. I have a real BB Preamp and the Perelandra sounds exactly like it. I am very happy with the build.
