How do I change tubes in my Effectrode pedal?

Swapping miniature tubes in Effectrode pedals is as quick and easy as changing a light-bulb. First disconnect the pedal from the mains power outlet. A tube can be removed by gently gripping and pulling the glass envelope whilst wiggling it in a circular motion. When replacing a tube make sure the pins are aligned correctly with the tube socket and gently push it into position. Never use excessive force to insert the tube as this may bend pins. Tubes in Effectrode subminiature pedals (PC-2A Compressor, Helios Fuzz and Fire Bottle boost) cannot be removed as these are soldered in position inside the pedal.
