Question Do the TonePrint pedals have some kind of built in safety protection which prevents the user from accidentally using the wrong polarity or 18V adapters instead of 9V adapters with them

No! It is therefore very important to make sure that your external power supply delivers the required 9V DC, 100mA, with a center negative pin. Using the TonePrint pedals with anything over 12V will destroy the pedal and void the warranty. This FAQ concerns the following products:
