How often should I replace tubes in my effects pedal?

If operated well within their ratings, good quality signal tubes can last 100,000 hours or more; that’s well over 11 years of continuous use. To extend tube life, we recommend that the pedal is allowed to warm-up for at least one minute after being switched on. This is to allow the heater filament in the tube to heat the cathode, which is coated with a layer of barium and strontium oxide. This oxide layer gets torn off the cathode, a process known as cathode stripping, if the cathode has not reached it’s correct operating temperature, ultimately shortening tube life.
