Why upgrade to PM Guitar Tubes?
Like guitar strings, tubes should be considered a consumable item! When it comes to amplifier maintenance, some people are content to change their tubes when the existing set have burnt out -but this can cause damage and additional wear to other components.
In order to avoid your tone becoming muddy and lifeless (unless that is what you are aiming for!) and to keep your amp running at its best you need to replace your tubes regularly. PM recommends replacing tubes at least every two years; the more often and aggressively you play, the faster your tubes will wear out.
The PM range was created to simplify re-valving an amp. We have picked what we believe to be the best sounding and most reliable valves from current production.
