    A medium-output power tube (generally 20-25 watts) often used in Fender® professional amplifiers including the Bassman®, Bandmaster®, Concert, Dual Showman®, Hot Rod™ Series, Pro Series, Super Reverb®, Tremolux™, Twin, Vibrolux®, Super-Sonic™, Blues Deluxe™, Blues DeVille™ and others. Available in many variations, its response is round, with a pronounced midrange character; strident and chesty with a super-bright and clean, powerful punch. Perhaps the most recognized signature tone for U.S. guitar music of all styles from the ’60s onward.

    Great dynamics and a very sweet, punchy tone with enhanced power rating and performance. More brilliant top end and a very full, pronounced and round low-frequency output. A solid replacement for stock performance.

    Matched quartet of 6L6-S tubes rated from power range 1-10. Each quartet has a specific rating (i.e. R2, R7, etc.) and is matched and biased to a specific output level.
