Anyone tell me a bit about the Mezzabarba MZero Overdrive?

This amp has been on my back burner for years. I keep putting it off since its really pricey and not too much talk about them.
But from what I see and hear on they seem amazing.
Anyone care to share their experience? What they might compare to?

I'm interested in this amp as well. Looks/sounds like an improved tweaked Soldano SLO. I like the incorporation of the presence & depth on the front... and the EL34 power section.

Inquiring minds and all...

I've heard it's a cross between a good Marshall and SLO. Mooncobra(Mike), Glip(Gary) and Inca(Rick) here on RT have owned them.

I had the mini one. Yup marshall and slo mix. I dug it and want the bigger Mzero

I owned an Mzero od and it was a killer amp. It sounded like a more raw, pissed off, darker SLO with much beefier bottom end and a more complete growl than the SLO, which may be why guys describe it as being Marshally too. I owned an SLO too and much preferred the Mzero (I personally think the SLO is overrated). Some of my other amps though had tighter lows, more complete growl (I'm very picky about that), and did better for leads and single note stuff, but I kept the Mzero because it sounded so big and beefy (it was the biggest sounding amp I had at the time), but then I got my atomica modded Marshall SLP and later a wizard mtl and those sounded at least as big, if not more and had more aggressive, complete growl, tighter, more defined lows, and were better for lead and single note stuff, so I sold it. If I didn't get my atomica, the Mzero may have been a keeper (even with the mtl possibly) but I felt the atomica beat in every way and made it unnecessary, but still a top notch amp

It's also worth noting that the production Atomica doesn't sound exactly like my Atomica modded Marshall (I like mine better), so it may have been a different story if I AB'ed the Mzero to the production version

Wow, I recently tried a Mezzabarba MZERO Overdrive and was absolutely blown away. I've been using a few Friedman BE100 for the last 6 years and like many of you have owned many other fine amps (Landry, 3rd Power HD100, Friedman BE100, Komet Concorde, Aiken, Suhr PT100, Bruno UG30, Two Rock CRSig, Bogner Shiva, Kingsley 30, Marshall JCM 800's, etc...

You have got to try one of these amps....the main impressions I have are that for a high gain amp this has the best clean channel I have ever found, and the gain channel is awesome. In reality the clean channel can go from very clean to very mean, with footswitchable boosts, and the gain channel takes it from there and goes way further.

On top of that, the amp sounds more huge than I've heard....just stunning.

I also tried the Z35 which is also mind blowing....it's a one channel and meant to be very vintagey......truly a volume knob riders one channel amp dream.

I know how it is when you get these gushing reviews and lots of superlatives....but you must find a way to try this amp as it is simply unbelievable how much better it sounds than anything else I've tried.

I can't believe that it's so relatively unknown...i see posts like the above from 2013....and on lots of forums there is a little mention of it here and there...but I have the feeling this thing is about to be discovered big time...I've seens pics of sammy hagar and joe satriani checking them out, and I hear Joe's next album will include tracks using it.

Anyhow...I expect to hear big things at mezzabarba in the near future.

I have an M Zero. It is an awesome amp. The descriptions of something between an SLO and a modded Marshall are pretty much accurate. If an SLO and a really awesome modded JCM800 style amp were to get together on a drunken, steamy summer night and have hot, sleazy sex in a Ferrari that resulted in an unintended pregnancy the Mezzabarba M Zero would be their illegitimate love child.... That's about the best I can describe it I think.....

I played one for quite a while at the 2016 LA Amp Show, and it felt and sounded really good, but had an odd high end frequency that bugged my ears after a while.

Could have easily been the way it was dialed, or the speakers, but it definitely prevented me from buying one that day at $4,000.

I'd probably grab a used one, but good luck selling the fucker, these days. It would need to be a smoking deal to get me to bite.

The amp is point-to-point hand made, with extra heavy transformers, very flexible via it's "feedback" knob, allowing either a darker-bluesier-classic rock performance, or a up-in-your-face aggressive more modern tones and feel. No change of tonality and feel between bedroom level and loud volume, once you set up you gain and eq. Very responsive Ch1, with a wide variety of gain settings, via the foot-switchable boost, with the addition of a gain pedal in it, Ch1 covers a lot of ground. Ch2 gives more natural added distortion and tube compression, a "leave it and forget it" deal, where the guitar volume comes to play here. Line out allows you to use the amp in a wet-dry set up. Completely transparent series fx loop.

Yes! I went ahead and bought it, it's an unbelievably good amp. Good description of it.
