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.

Stocked in “medium” power ratings; also available as special orders with “low” and “high” power

ratings (please contact customer service for these).

Available as singles, duets, quartets and sextets.

Groove Tubes power tubes are matched and rated in low, medium and high output levels.

Most amp manufacturers bias their amps for tubes in the “medium” range, and replacement of stock tubes frequently do not require re-biasing if “mediums” are purchased.

• For softer feel, quicker distortion and creamier tone, we suggest “lows”
• For more dynamic headroom and tighter, quicker and harder overall response, we suggest “highs”.

Lows and highs are more likely to require re-biasing by a qualified service technician to meet your

performance preferences.
