## Description

Electro Harmonix EL34 Quartet Matched Pairs Power Tubes

Review: J’ai fait l’acquisition de tube à vide EL 34 de la firme Electro Harmonix russe d’une précision déconcertante un son riche du détail une douceur hallucinante je les conseille fortement
Review: I put these tubes in a Peavy Windsor. I also switched out all my preamp tubes with Electro Harmonix 12AX7. These tubes made it sound like I bought a new amp. The Windsor is supposed to be a sort of Marshall single-channel rock machine knock off, but you won't get that killer sound unless you get the stock tubes out of there. These tubes are straight up amazing for the price. My ears hear warm, buttery, cascading natural overdrive when you keep you preamps low and let the volume knob push the power tubes into overdrive. I like em. A lot.

Used in a mesa dual rectifier. Sounds great and really shows that it should have been an el34 amp all along.
