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.
This is one of three Aion PCBs that I built a few months back. Great PCBs and the instructions are spotless and very useful. This is a great sounding smooth distortion circuit, but I did some mods…
Modifications or part substitutions
Too much gain for me, so I simply swapped the 1M gain pot for a 500k like in the original tube screamer. I also found it slightlt dark, so I swapped R19 for a 7k and R20 for a 13k. Now it sounds more like a tube screamer with the tone @ 2 o’clock but with the added benefit of the baxandall tone stack!
