The Mesa Boogie 6V6S STR 417 power tube is all about classic American tube tone from yesteryear. Extremely sweet & bubbly with a beautifully deep bass & spacious shimmering highs, this tube defines vintage “Deluxe” styled tone and is the standard tube in their California Tweed & Fillmore 25 – It’s also a great substitute in the Mark I, Mark IV & Lone Star when used with their “Tweed” Switch feature or in their Triple Crown amplifiers (no Tweed switch necessary). Please see your amplifier owner’s manual for correct use of this tube.
