Tung Sol Flasher _hot_ -

Note: Tung-Sol is best known for the 6550 and 12AX7, but the “Flasher” refers to a specific gimmick in their 6L6G/6L6GA tubes from the 1940s-50s, and modern reissues that mimic this effect. 1. What Is It? The “Flasher” is not a pedal or a standalone device. It is a nickname for vintage Tung-Sol 6L6G / 6L6GA vacuum tubes that exhibit a visible blue glow inside the glass envelope that pulses or “flashes” in time with the bass frequencies of your guitar or music. Modern reissues (e.g., Tung-Sol 6L6G STR) have revived this aesthetic. 2.
