12 AT7-EH double triode tube

Ideal for high-quality Hi-Fi audio applications as well as music (guitar amps, bass, etc.). Use it as a low-gain substitute for the 12AX7 to achieve a clearer sound and thicker "crunch" tones in guitar amps or effects pedals.

Electro-Harmonix tubes are a completely new design and of excellent quality. Many manufacturers use rebranded Electro-Harmonix tubes in their amplifiers. If you are looking for high-quality tubes at a very reasonable price, Electro-Harmonix tubes are for you.
