The Express 5:50 Guitar Amp Head is part of a very popular line of amplifiers from the people at Mesa/Boogie. This is a two-channel amplifier that delivers 50 watts of tube driven power. You can buy the Express 5:50 as a head, or as a combo amp. There are five 12AXY tubes in the preamp section and two 6L6 tubes in the power amp section. The amp gets its name from the Mesa/Boogie Patented Multi-Watt Channel Assignable Power system. This system allows you to select one power tube operating in pure Class A Single-Ended, producing 5 Watts, two tubes operating in pure Class A Push-Pull, producing 25 watts, or two tubes operating in the Mesa/Boogie proprietary Dyna-Watt Class A/B power, producing 50 Watts. The Express 5:50 also features a tube-buffered Spring Reverb, and a tube-buffered effects loop.

Each channel features its own Gain, Treble, Mid, Bass, Reverb, and Master controls. Each channel has a toggle switch to alternate between two modes. Channel 1 has Clean or Crunch and Channel 2 has Blues or Burn. Both channels share a five-band graphic EQ that you can select if you want to use the sliders or a preset contour via toggle switch. The Express 5:50 also has a separate solo control that supplies a boost to the signal for lead sections. The included four-button footswitch toggles Channels, Reverb, Graphic EQ, and Solo.
