The clipping diode array is modular, pop off the back cover and you can swap out for a different array. PCBs are available to make your own module - if you happen to believe that some diodes are magical you are free to go on a side quest and track them down! FLWR ships with one module containing two array options. Select 1 or 2 on the CLIP control to engage them. The stock diode arrays are designed to be very subtle, but more extreme arrays are possible.
FLWR uses the same WHATEVER power supply featured on EUNA and OAMP - the pedal will accept 7.5 to 35 volts of AC or DC in either polarity with absolutely no change in tone or power to the circuit.
