Nobody understands the importance of tone more than Electro-Harmonix does. From its beginnings in the 1960s, Electro-Harmonix has listened; whether to customers' input or the product itself. EH vacuum tubes are revered by lovers of good tone, and it doesn't matter if you need them to power a guitar amp's distortion and sustain, or achieve hi-fi audio purity. Electro-Harmonix tubes will perform.
