The Mesa Boogie Triple Rectifier 150W is a high-gain, all-tube guitar amplifier head built for maximum power, tonal flexibility, and professional performance. It delivers up to 150 watts through six 6L6 power tubes (or optional EL34s) and uses five 12AX7 preamp tubes along with three 5U4 rectifier tubes. The amp offers three fully independent channels, each equipped with its own gain, EQ controls, presence, and master volume. Channel 1 provides Clean and Pushed modes, allowing everything from shimmering clean sounds to slightly overdriven crunch tones. Channels 2 and 3 each offer Raw, Vintage High Gain, and Modern High Gain modes, covering classic rock drive, saturated lead tones, and the tight, aggressive distortion associated with modern metal.

A key feature of the Triple Rectifier is the selectable rectification system. Players can choose between tube rectification for a warmer, more elastic response, or solid-state diode rectification for a tighter and faster attack. The amplifier also includes a Multi-Watt power system that allows each channel to be switched between 50 watts and 150 watts, making it suitable for both small venues and large stages. The amp’s bold/spongy switch further adjusts power response, acting like a built-in variac that changes the feel and saturation.

The Triple Rectifier includes a fully buffered, footswitchable effects loop with its own send-level control, a footswitchable solo boost, and multiple speaker output options with different impedance settings. It is known for its rugged construction, being hand-built in Petaluma, California, and designed to withstand demanding professional use. Weighing approximately 48 pounds (about 22 kg), it is built solidly and engineered for touring reliability.

Overall, the Mesa Boogie Triple Rectifier 150W is recognized for its massive gain structure, wide tonal range, exceptional headroom, and professional-grade features. It is used extensively in rock, metal, and modern high-gain music, but also provides enough versatility to cover
