Condition
Excellent working condition with normal rack wear from use. Both channels are strong, balanced, and responsive. All controls, switches, and jacks function properly. Tubes are healthy with plenty of life left, and the fan runs smoothly. This unit delivers the tight, punchy, unmistakably "Boogie" power section tone these amps are known for.
Description
The Mesa/Boogie 50/50 is one of the most respected stereo tube power amps ever built — a true heavyweight from the golden era of rack gear. It's the perfect match for preamps like the Mesa Studio Pre, Triaxis, Quad, or any high‑quality tube or digital front end that needs real iron behind it.
Each channel runs a pair of 6L6s with independent Presence and Resonance controls, giving you the ability to dial in everything from tight, focused punch to wide, blooming low‑end. The 50/50 has the fast attack, clarity, and authority that made Mesa rack rigs the standard for touring players throughout the '90s and early 2000s.
If you want a stereo tube power section that feels huge, reacts instantly, and stays musical at any volume, this is the one.
