What is the best 12AU7? Why Choose Electro Harmonix EH 12AU7 pre-amp valves?

The EH 12AU7 or EH ECC82 is popular because it delivers both consistency and superb tone. The manufacturing process means there is little variation between the valves which is important when your valves need to be replaced.

This valve will also give you an upgrade in tone if your valves are of poor quality when supplied or worn. It is a sad fact that many amplifier manufacturers use cheaper valves to keep the cost down. Upgrading to EH valves will improve your tone and performance.
