A portable 20 watt mini head amp, the invective.MH amplifier was created in a second collaboration with Periphery guitarist, Misha Mansoor. The invective.MH amplifier packs all of the best tones from its 120 watt big brother. 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 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.

A versatile and little powerhouse
A versatile and little powerhouse of an amp. Clean voicing is nice but the gain section with the tight and boost is where it is at for the metal!

Killer modern tube tone in a small package
Purchased for practice at home and home recording. Tone is usually the first thing sacrificed when playing at low volume or with headphones, NOT THE CASE HERE! I can’t believe how much this amp RIPS and how great it sounds at any given volume. Loud enough for punishing metal riffs at full stage volu...

Massive tone for such a small package.
This head is fantastic. There is so much variability that it will suit all needs for anyone playing metal. The clean channel is very clean especially when comparing it to the 6505 MH. On the gain channel the gate/tight/lead instantly change the way the amp sounds and further diversified the amp. You...
