Peavey invective.MH 20-Watt Mini Tube Amp Head - High Gain | No Limit Guitar Co, Idaho Falls
The Peavey invective.MH is Misha Mansoor's signature amp head reimagined as a compact, 20-watt mini tube head built for players who want devastating high-gain tones without the stage-filling wattage. Rooted in the same preamp architecture as the legendary 6505, it delivers the tight, aggressive response that made the full-size invective a favorite among modern metal and hard rock players. Available now at No Limit Guitar Co in Idaho Falls, this is a serious amp for serious players.
Product Overview
The invective.MH is built around 3 x 12AX7 preamp tubes and 2 x EL84 power tubes, housed in a black leatherette cabinet that measures 14" wide and weighs just 16.6 lbs. Switchable between 20, 5, and 1 watt, the amp's power attenuation circuit lets you push the tubes into saturation at practice and rehearsal volumes without losing the feel and tightness the invective is known for. A speaker defeat switch and 1/8" headphone output extend the amp's usability into silent practice territory.
Two channels cover the full range of modern playing demands. The Clean channel features a 2-band adaptive EQ for dialing in pristine, clear tones, while the Lead channel delivers the high-gain firepower the invective is famous for, complete with a 3-band EQ, Master Resonance, and Master Presence controls. The preamp design draws heavily from the 6505 circuit — one of the most respected high-gain platforms in modern guitar amplification.
The invective.MH's noise gate is engineered for an extremely fast cutoff, eliminating unwanted noise between notes and riffs without affecting your attack. A cab-emulated XLR direct output with ground-lift control and a speaker-simulated USB output make it equally capable as a recording and direct-performance tool. Tube Status Indication rounds out the feature set, monitoring your EL84 power tubes and alerting you before a failing tube becomes a problem on stage.
Ideal For
- Metal and hard rock guitarists seeking a high-gain mini tube amp head with tight, aggressive tone
- Players who want a Misha Mansoor signature amp for rehearsal, small gigs, and direct recording
- Home and studio players who need switchable wattage and a headphone output for silent practice
- Guitarists integrating a pedalboard via a footswitchable buffered effects loop
- Players looking for a compact 6505-voiced tube amp head in Idaho Falls or online
Key Features
High-Gain Lead Channel with 6505-Voiced Preamp The Lead channel is built around the same tightly voiced preamp architecture that defines the 6505 sound — aggressive, compressed, and focused, with 3-band EQ, Master Resonance, and Master Presence for precise tone shaping. This is the core of what makes the invective.MH a legitimate metal amp in a small package.
Super-Tight Noise Gate Peavey engineered the invective.MH's noise gate for an incredibly fast sound cutoff, making it exceptionally effective for high-gain playing styles where noise and feedback between notes are a constant challenge. It cuts cleanly without affecting pick attack or sustain.
Switchable Power Attenuation (20W / 5W / 1W) Drop the wattage to push the power section into saturation at lower volumes — all three settings maintain genuine tube response and feel. The speaker defeat switch and headphone output extend this further for completely silent practice.
Cab-Emulated XLR Direct Output The built-in cab-simulated XLR output with ground-lift control lets you send polished, speaker-emulated tone directly to a PA or audio interface without a microphone or cabinet. Paired with the speaker-simulated USB output, the invective.MH is a complete direct-recording solution.
Comprehensive Footswitch Control Two footswitch jacks — included with a 2-button footswitch — give you hands-free control over channel switching, the Tight voicing, Boost, Gate, and the buffered effects loop. Few mini heads offer this level of live performance control.
