Invective MH Mini Amp Head

Peavey invective.MH Mini 20W Tube Guitar Amp Head

The Peavey invective.MH is a compact, high-gain tube amp head designed for modern players who demand tight, aggressive tone and pedalboard-friendly flexibility. Developed in collaboration with Misha Mansoor, this mini head delivers the signature sound and performance of the full-size invective in a portable format.

Powered by 2 EL84 power tubes and 3 12AX7 preamp tubes, the invective.MH delivers everything from pristine cleans to crushing high-gain tones. The clean channel provides a clear, responsive foundation—perfect for pedals—while the lead channel is inspired by the legendary Peavey 6505, offering tight, articulate distortion ideal for modern rock and metal.

An onboard attenuator lets you switch between 20W, 5W, and 1W, making it easy to achieve great tone at any volume level. The amp is packed with advanced features including a built-in noise gate, boost, effects loop, and multiple recording outputs—making it equally at home on stage or in the studio.

With USB output, XLR direct out with speaker simulation (MSDI), and a headphone output, the invective.MH is a complete solution for recording, silent practice, and live performance setups.
