Mesa Boogie 5881 / 6L6 STR 425, Matched Pair
The MESA 5881 STR 425 is a military-spec 6L6 power tube engineered for high-voltage applications and long-term reliability. Built to withstand demanding conditions, this tube excels in delivering bold low end, rounded mids, and a naturally subdued top end—making it well-suited to jazz, fusion, blues, and other styles where warmth and headroom are key.
