Peavey Invective MH 20/5/1-watt Tube Head Reviews
The Peavey invective.MH takes Misha Mansoor’s signature amp head and packs it into a 20-watt, 2-channel design. This mini head retains many of its larger sibling’s player-friendly features — the cab-simulated output, super-tight noise gate, and footswitchable functions — while providing everything a guitarist needs for rehearsing and playing small gigs. And, of course, the invective.MH delivers the tight high-gain tones you’d expect from a Misha Mansoor signature head. If you’re searching for brutal, hard-hitting tones but don’t need to fill an arena, then you can’t go wrong with the Peavey invective.MH — it’s everything you want and more.

This little thing rips
It's great. You have a ton of tonal options with this amp. Peavey knocked it out of the park with this one.
Best Peavey tube head ever.
I get all kind's of metal tones with this head. It's very loud and I just use 1 watt. My favorite head ever.
Everything at 12:00
The Lead channel has a red LED light. The gate button makes everything sound tight when playing. the 20w-5w-1w switch in the back next to the 16Ω and 8Ω switch serves as the perfect volume knob. 20w is the loudest, I used 5w for a live performance and it blended nicely with the backing tracks going thru the PA system. The MSDI (mic simulated direct interface) output has a SPKR button that functions as a built in IR (impulse response) for recording. My favorite clean channel settings are as follows:
Gain: 3
Low: 7
High: 8
If you plug in your headphones, I highly suggest only sticking to the clean channel. Not only that, but the Peavey Invective MH has a GRND LIFT button if you're into that.
Amazing Little Workhorse
While this little guy is only 20 watts, yes. Do not be fooled by this, as it holds enough power for live purposes, and not just home use. If you find trouble getting enough volume in a full band setting, know that its not a power issue, but an issue of not enough speakers to project the sound. Essentially, add more speakers, and you'll get more volume. Don't be tricked into thinking you need a powerhouse of 50, or 100+ watts just to play with a band. That is only unless you prefer the tonal, and headroom difference of larger valve heads of course. Otherwise, it's a fantastically built, looking, feature-packed, and most importantly, great sounding little amplifier. Well done Peavey, well done..
Well made amp
Sold my MTS 15 and got this. No regrets .... this is a good low volume room amp. Gain Chanel resembles my Horizon apex with more clarity. Noise gate cuts a little early for leads and would be better if it were adjustable. Effects loop works very well. I've gone through many mini amps looking for what this amp does. Good job peavey...
Great sounding amp for metal.
Great sounding amp that has massive amounts of gain. Just don't expect too much out of the noise gate considering it has no controls other than on and off. I paired mine with the invective 2x12 cabinet. Cranks out on just the 1 watt setting with the post gain only half way.
Versatile little head
I'm very pleased with this amp. The tones are nice and what I expected from a Misha sig amp. I love the convenience of a direct out and speaker defeat, not to mention the built in power soak. Highly recommend for metal especially with clean parts.
Superb Tone and Clarity in an extremely convenient box.
The tight feature and the gate are just amazing! It has all the thick and rich tone of running a clean boost without needing an additional pedal in the circuit. The only thing I don't like about this product is that it requires 2 separate footswitches to change channels and add or remove the boost features. But honestly, it's made to be a bedroom/small studio amp so it's not really a big deal.
Great little amp with some (very) minor flaws
I got this amp about a week ago. I've been a big fan of the Peavey high-gain sound for quite a while--I used to play through an OG 5150 212 combo--and I was very excited to have a new Peavey tube amp. For the most part, I'm very happy with the amp. I think overall it's a crazy value for the price point. I haven't been able to really turn it up and blast it yet, I've been playing at low-ish volume on the 1-watt setting. But here's what I'd say so far:
Pros:
- Lots of gain on tap (though not quite as much as I had expected, but I like my sound *super* saturated, so...)
- High gain tone is very nice, dynamic, well-balanced
- Sounds good (not thin or fizzy) even at very low volumes on the 1W setting
- Responds well to pedals in the FX loop (see below)
- Sounds even better (much fuller) with an EQ pedal in the FX loop (I use the MXR 10 band EQ, which is amazing)
- Very useful and cool on-board features: boost, gate, tight, etc.
- The on-board 'boost' and 'tight' functions work very well together, sound great
- Clean channel sounds nice (good clean slate for pedals)
- Nice looking, solid fit and finish, lightweight
Cons:
- If you are a gain hound like me, you might need a little gain boost to get it *really* saturated at low volumes
- The on-board noise gate is, to my ear, too aggressive. It works *okay*, but it cuts out some of the punchiness and fullness of the tone along with the hiss and buzz (I've opted to used a noise gate pedal in the FX loop instead)
- Like many amps, the post-gain (i.e., volume) control is *very* sensitive. Even minor adjustments make a big difference in volume
Overall, I would recommend this amp, especially to anyone who is a Peavey fan or a Periphery/Misha Mansoor fan. I suspect the most direct competition for this amp is the PRS MT15 (Mark Tremonti) amp head. I've never played that amp, but I'd definitely like to. However, this Invective MH has a number of features that the MT15 does not, and it's also $... cheaper new. So in that sense, the Peavey comes out ahead.
Little box of horrors
My previous live rig was a block letter 5150, I wanted something similar for bedroom volumes and this head delivers!!! Currently using it through a peavey 112-6 cab and at 20 watts it pushes the bottom just right. The gate and boost are great additional features although I wish there was control over the gate as I find it could be backed off a bit for my preference.
4 stars only because it could have used some control over the gate and because the gate and boost are not foot switch controlled separately, you can activate both or none only.
Super impressed with the tone!
Good amp for sure but..... do not be misinformed buy [ " modern day infomercial host" "aka you tubers" ]like i was as to the realistic capabilities of this amp
take your time and really think about ALL the tasks you are going to need to use your amp for? then ask your self again ignoring what you tube says for a min, would a 20watt amp be able to deliver the power and decibel range that you need? I myself did not do this, I did not sit down and really use my own common sense. I just made the purchase on the more than likley paid word of those handful of you tube gear channels all of us gear nerds anoy our spouses with. LOL.
After several attempts of playing with a drummer in a 15x15 practice studio I decided to return my Invective MH and try to find something with more wattage.
