GE 6V6GT tubes are extremely long-lasting and are built to handle abuse. Similar to Raytheon (and unlike RCA), GE is still a household name, and we can attribute a very small portion of their success to GE’s ability to make kickass vacuum tubes. We have found GE power tubes in Fender, Gibson, Valco, Supro, Airline, Hammond, and Danelectro amplifiers. Tonewise, expect classic robust American guitar tone with lots pronounced lows and highs.
