Matched pair of 6L6 vintage-voiced power tubes.
The MESA/Boogie 6L6 GC STR 441 is an exceptional vintage-voiced 6L6 power tube with superb low end, neatly tucked mids and an exceptionally smooth, tapered top-end for a warm, rich and sweet tone. They help provide the Treble and Presence Controls with an extended usable range without adding unwanted, detached “buzz,” "sizzle" or harshness.
