Aion FX implementation of the UBE adds two modifications a clipping diode switch and a second switch to change out the global feedback resistor The original Runoffgroove article recommends selecting this resistor for based on whether you ll be using single coil pickups or humbuckers so we took the step of putting it on a switch so the pedal can be used in any scenario without heating up the solde...
