The legacy of the best-selling metal amp of all time, the sound of an all-tube amplifier, and the features you need to silently record the ultimate tone... designed in conjunction with the talented Misha Mansoor of Periphery, the Peavey invective.MH is a tube-tone monster!

Unlike many high-gain amplifiers, the invective.MH all-tube mini head has an amazing clean channel. Designed to work extremely well as a platform for those that love pedals, channel one features independent Gain and Tone controls.

The Lead channel is based on the legendary Peavey 6505 and adds many heavily-requested new features to create the ultimate tone. The Gate control allows for extremely loud and tight palm muting, while the Tight button actually reduces some gain and adds string clarity, giving the effect of tightening up the crunch. The Boost function allows for increased output via footswitch, perfect for soloing.

The Master section allows user access to Resonance and Presence controls that were first found on the original 6505, where they contribute to its iconic tone.

The back of the amp makes this one of the most versatile tube amps on the market. An on-board dummy load allows the speaker output to be muted for headphone use or silent recording, a Peavey first. Whether using the XLR output or the USB out, the invective.MH is perfect for recording.

The built-in footswitchable effects loop and on-board 9v pedal power allow the user to easily add their favorite effects to the signal path.

A compact amp with massive tone, the invective.MH is one of the most versatile and in-demand amplifiers ever made.

The invective series was designed in collaboration with Misha Mansoor (Periphery) to be the ultimate starting point for distinctive metal tones. From rich, chiming cleans to full-bore distortion, the invective.MH delivers the versatility modern medal players need to shape their own signature tone.


Driving the invective.MH are three 12AX7/ECC83 preamp tubes and dual EL84 power tubes. Whether you’re playing intricate arpeggios on the clean channel, or chugging palm mutes with full distortion, the invective.MH delivers the dynamic punch and tactile response you only get from tubes.


The invective.MH delivers something few high-gain amplifiers do — an amazingly rich and vibrant clean channel that takes pedals like a champ.


Peavey’s Microphone Simulated Direct Output emulates the sound of a microphone placed three inches from the speaker cone. Connect the USB output to your computer, and you’re ready to record studio-quality amp tones direct to your DAW — no microphone required.
