Groove Tubes Gold Series GT-6L6-S Matched Power Tubes Medium (4-7 GT Rating) Duet

The Groove Tubes Gold Series GT-6L6-S are medium-output power tubes (generally 20–25 watts). 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. These power tubes offer great dynamics and a very sweet, punchy tone with enhanced power rating and performance. With a more brilliant top end and a very full, pronounced and round low-frequency output, Gold Series matched power tubes are solid replacements for stock performance.
