Mesa/Boogie Dual Rectifier Tube Guitar Amplifier Head (100 Watts)

Get the sound of modern rock and metal for decades! The Dual Rectifier's three footswitchable channels will take you from glassy cleans to brutal overdrive.

It's been more than 25 years, two generations of guitarists and several musical trend-cycles since the Dual Rectifier first unleashed its crushing wall of gain on radio. In that time many have mimicked, modeled, dissected and plagiarized it, but it remains firmly planted at the center of heavy music; a Rock icon.

Over a decade ago the Recto underwent a massive facelift that greatly expanded its versatility and took what was a 2 Channel amp aimed squarely at high gain only to a 3 Channel amp capable of roaming any style confidently.

While still leaving the widest, deepest footprint in heavy music, the Dual Rectifier has become the amp of choice for a long list of chart topping devotees outside the world of heavy.


Better sounding and better feeling than any 2 or 3 Channel version that came before it, Mesa had only one mission: To build the best Rectifier yet. Not an easy task but now with their patented Multi-Watt 50/100 (watt) Channel Selectable Power, an Improved Effects Loop, Channel Assignable Rectification with Rectifier Tracking, a dedicated Tuner Out with Mute and an updated Footswitch, the Dual Rectifier is more capable than ever before.

But what really has us most excited isn't all the latest features you see on the front and rear panels. While these are great and really useful, it's the TONE and range that has us most fired-up!

Mesa has unearthed a lot of secrets since launching the original Dual Rectifier and they have read more put this knowledge to use in the latest rendering you see here. Improved CLEAN and PUSHED Modes in Channel 1. Improved Modes in Channels 2 and 3 include a more soulful, earthiness in RAW, thicker layers of harmonics and more liquid gain in VINTAGE and tighter gut-punching attack in MODERN.

the tone and sound from this head fresh out the box is so satisfying. the clean channel is crystal clear and the options for 3 different "modes" for each channel is such a nice feature of this amp. but lets be real, you're buying this for the gain and that desired 'Recto' metal/rock sound from channel 3. Putting a OD/Boost in front of channel 3 on modern is really the sweet setting for metal/hardcore riffing and cleaning up any heavy bass tones that all Mesa Rectos have. i haven't been more excited about a piece of equipment. worth every dollar.
