MESA/BoogieDual Rectifier Multi-Watt 3-Channel 50/100W Tube Guitar Amp Head - Blackout

Its three independent channels provide eight total modes, from Channel 1’s Clean and Pushed voices to the Raw, Vintage High Gain and Modern High Gain settings available on Channels 2 and 3. Each channel carries independent tone and gain controls, channel-assignable 50W or 100W multi-watt power and selectable Recto Tracking rectification. Four 6L6 power tubes supply substantial Class A/B output, while the Bias Select switch supports EL34 tubes for an alternate power-section character. A fully buffered, footswitchable effects loop, Solo function and included six-button footswitch make the amp ready for detailed stage control. Three Channels for Clean, Crunch and Gain The multi-watt three-channel design expands the Dual Rectifier beyond its original high-gain focus with three independently voiced channels that can be set up for clean, crunch, rhythm and lead work. Channel 1 offers Clean and Pushed modes for clear, responsive sounds or more assertive breakup. Channels 2 and 3 each offer Raw, Vintage High Gain and Modern High Gain modes, providing contrasting routes to Rectifier overdrive. Raw mode supplies a more open, lower-gain response, Vintage High Gain emphasizes the broader, saturated character associated with classic Rectifier tones, and Modern High Gain delivers a tighter, more immediate option for aggressive playing. With independent controls on every channel, players can establish distinct gain structures and EQ settings without compromise. Channel-Assignable Multi-Watt Power and Rectification Each channel includes its own 50/100 multi-watt switch, allowing players to assign either output level to suit the sounds and response they want from that channel. In the 50W setting, the power amp operates with 2 power tubes; at 100W, all 4 power tubes are engaged for greater output and authority. The amp’s patented Recto Tracking system also makes dual rectification channel assignable, letting players choose tube or silicon-diode rectification for each channel while automatically matching the rectifier configuration to the selected power-tube complement. Combined with the BOLD/SPONGY power switch, this architecture gives the power section a deeper role in shaping the amp’s feel and response. Four 6L6 Tubes With EL34 Compatibility Four MESA 6L6 power tubes drive the Dual Rectifier’s Class A/B power section, providing the headroom, low-end weight and dynamic range expected from a full-size Rectifier head. The Bias Select feature supports EL34 power tubes as an alternative, allowing players to tailor the amplifier’s power-tube character without manual rebiasing. Five MESA 12AX7 preamp tubes supply the gain and tonal shaping that define the amp’s broad range of clean, pushed and high-gain voices, while 2 MESA 5U4 rectifier tubes support tube-based operation when selected. Maintenance-free fixed bias and convection cooling keep the design practical for regular rehearsals, recording sessions and live performance. Footswitchable Control for Advanced Performance Rigs The included 3x3 six-button footswitch provides direct access to Channels 1, 2 and 3, along with tuner mute, effects loop and Solo functions. A fully buffered series effects loop includes Send Level control and can be footswitchable, channel assignable or true bypassable, making it adaptable to pedalboards and time-based effects placed after the preamp. The True Bypass switch removes the effects loop, Output and Solo level controls from the signal path when desired. A global Output level control and global Solo level control provide further performance management, while external switching jacks, a tuner output and Slave output with level control support more elaborate live and studio rigs. Its marine-grade Baltic birch cabinet, aluminum chassis, 41 lb. enclosure and included fitted slipcover support transport and regular stage use, while the 16-ohm, dual 8-ohm and dual 4-ohm speaker outputs accommodate compatible cabinet configurations. For guitarists seeking a versatile Rectifier with channel-by-channel power and rectification control, extensive footswitching and an exclusive Blackout presentation, the MESA/Boogie Dual Rectifier multi-watt three-channel tube guitar amp head delivers a broad, performance-ready take on a high-gain rock icon.
