Peavey Invective.MH Guitar Amplifier Head (20 Watts)

Designed with help from Periphery's Misha Mansoor, the 20-watt invective.MH has two footswitchable channels and packs a heck of a punch from a tiny package.

In a second collaboration with Periphery guitarist, Misha Mansoor, the invective.MH amplifier packs all of the best tones from its 120 W big brother into a much more portable 20 W mini head format. At the heart of this little monster is a pair of EL84 power tubes shaped by three 12AX7/ECC83 preamp tubes, providing everything from pristine cleans to the infinitely chunky gated d'jent destruction.

The many features of the invective.MH will satisfy even the most discerning of gear heads. The onboard T.S.I. (Tube Status Indication) circuit helps the user diagnose a problem with the power tubes. The bias adjustment pot is located on the top of the small, rugged chassis. Additionally, foot switches allow the invective.MH to engage or disengage the tight voicing and any combination of Gate and Boost on the Lead channel, respectively. There's also an independently foot-switchable buffered effects loop.

If there's one key takeaway, don't be deceived by the size or format of the invective.MH. No matter the venue, this mini amplifier has plenty of oomph for small-to-medium sized gigs and can even work as a backline stage monitor with its attenuator switch directing power at 20 W, 5 W, or 1 W to suit the need.

On the clean channel, adaptive low and high EQ help find the sweet spot with ease. The lead channel provides a three-band EQ. Master Resonance and Master Presence pots help shape the tone. In addition to its new sounds, the invective.MH has all of the recording hooks and flexibility read more of the other Peavey MH amplifiers, including MSDI (Microphone Simulated Direct Interface) Output with XLR and ground lift switch, speaker-simulated USB, speaker defeat switch, power attenuator, headphone out, and more. Dual quarter-inch TRS footswitch jacks allow for ease of MIDI control.

Footswitch included.

Bottom line up front... this is single-handled one of the best purchases I've made in the last 10 years. This amp IS NOT a one trick pony, and if you are looking for something small that is versatile and has a metal edge to it, then this is the one for you.I've been searching for quite some time to find "my" sound. I've had many amps throughout the years (and many I wish I could get back, :sob:), but lately I've felt like what I was doing wasn't me - that I was just mimicking someone else. Funny statement, since I'm writing about a signature amp lol.So on a whim, I purchased this amp. I watched all the reviews, and wondered if I made the right choice. I mean, how good could it really be? It's just another 5150 clone, right?I was completely wrong. I set everything to noon, hooked everything up (using a harley benton 2x12 with V30s), and flipped the switches. I was completely floored with how clear and articulate everything sounded. With some minor tweaking, I was able to get a clean sound that is well rounded, with just enough chime to ensure it cuts through the mix. If the clean channel was all it had, it would be perfect. But we all know this machines roots are in the original 5150/6505 bloodlines, and it doesn't disappoint. I've ALWAYS loved the 5150 range, but this modern take on an industry standard amp has me floored. I can dial it in the way I want, with all the little bells and whistles to give it that extra edge. I love that there is a gate built in, and that the boost read more if fully usable (if you even need it). I really like that the tight switch changes the character of the lead channel, and gives you something more akin to the gain structure of the 5150 of yester-year. All of my notes were articulate, and all of my chords hit me in the chest. If I buy another amp in the future, I will get the full size invective, no questions ask. Thank you zZounds, thank you Misha, and thank you Peavey.Pros:Great Cleans Great Leads Gate Tight Boost Presence Resonance Includes the kitchen Cons:It's not the 120 watt model :D
