The Peavey invective.MH takes Misha Mansoor’s signature amp head and packs it into a 20-watt, 2-channel design. This mini head retains many of its larger sibling’s player-friendly features — the cab-simulated output, super-tight noise gate, and footswitchable functions — while providing everything a guitarist needs for rehearsing and playing small gigs. And, of course, the invective.MH delivers the tight high-gain tones you’d expect from a Misha Mansoor signature head. If you’re searching for brutal, hard-hitting tones but don’t need to fill an arena, then you can’t go wrong with the Peavey invective.MH — it’s everything you want and more.

From pristine clean to punishing high gain

To pull off his genre-defining range of tones and techniques, Misha Mansoor requires an electric guitar amp head that delivers top-quality tones from crystal clear to over-the-top distortion. The Peavey invective.MH more than obliges. The Lead channel is voiced after Peavey's legendary 6505 tube amp line, and the Clean channel is specifically engineered to deliver a completely clean tone at any volume level while also having footswitchable options to push it a bit harder. No matter what shade of gain you need, the invective.MH has it covered.

Loaded with features for today's player

The Peavey invective.MH all-tube amplifier head is packed to the brim with added features that are sure to benefit players wanting the same tonal flexibility as many modeling units. A noise gate is featured on the front of the unit that boasts an incredibly fast response — perfect for precise palm-muted riffs. The amp's power attenuator dials it down from a club-friendly 20 watts to rehearsal-friendly five watts to a bedroom-friendly single watt. And a buffered effects loop allows you to integrate your pedalboard and other external processors.

Powerful switching

Not only does the invective.MH sport a bevy of player-friendly features, but it also offers a brilliant array of switching options, allowing you to access all your tones quickly whether at rehearsal or onstage. Dual 1/4" TRS footswitch jacks allow the invective.MH to engage or disengage the Tight voicing and any combination of Gate and Boost on the Lead channel. The effects loop is also footswitchable.

MSDI direct output

As Sweetwater knows, silent stages are becoming more and more prevalent in every genre of music. The invective.MH caters to this with its MSDI direct output feature. You're able to send a high-quality, cabinet-simulated signal to your front of house or recording console. And the ground-lift control ensures that your audience hears nothing but top-notch sound.

  • Misha Mansoor’s signature amp head packed into a 20W, 2-channel design
  • Preamps designed around the popular 6505 sound

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
