I’m in the process of changing to Temple pedal boards. The issue with the Eventide pedals is that nothing will stick to the base and I do not want to remove the rubber pad or adhere the Temple mounting hardware over the SN tag. I flipped the base over and there is a slight bit of compression from the rubber base to the circuit board. I powered up the Pitchfactor and there were no issues. I cleaned the base with alcohol prior to flipping. 

Long term, could there be any issues? It would be nice if Eventide would have blank bases available.
