What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Mesa 4/12
This is my second Mesa cabinet , and just as the first one it sounds nothing short of superb. As for sweetwater they are the only company I would ever even consider ordering something like this from. Now that's out of the way let's get to the not so good . This being one of the most expensive cabinets on the market I would think Mesa would do a bit of a better packing job . The box was pretty hammered when it got to my house , and the most irritating thing was there was a hole on the back of the box . Of course whatever hit the box hit the cab as well . Nothing severe , but it did dent and break the tolex on the back cover . Being a fairly serious collection I like all my stuff pristine. Definitely has no reflection on sweetwater , but it was a learning experience. I would recommend driving to sweetwater or another location to pick up the cabinet in person this way it doesn't go anywhere near a fedex truck .

TOTAL QUALITY!
This Mesa Boogie 4x12 is unlike anything I have ever played through before. I coupled it with a Peavey 6505+ high gain amplifier and this combination is amazing and perfect for my metal taste. The low end this cab delivers is intense and I feel these Vintage 30s flowing through me every time I jam through it.

Mesa always ensures they deliver total quality amps and cabs. This is what we are paying for and I was tired of settling on something when this was all I needed. Thanks to Sweetwater for making sure the shipping and receiving went smoothly. I love this cabinet!!

Superb 4x12!
This is a fantastic cab. Solid construction, great looks, built-in casters, free cover all make this a 'top of the line' cab- but the sound is AMAZING!! Makes a perfect pairing with my Mesa Boogie Mark V 35. HUGE shout out to my rep David Winkert who always helps me find the right item I need. I AM LOVING THIS CAB!!!!!!!!
by Hank from Maryland on
It’s a Mesa. Plain and simple
This cab doesn't need an introduction. It's a Mesa. Enough said.

I'm using this with a 2020 Black Jute Triple Rectifier and a Peavey Invective.

It doesn't get any better than this.

Mesa Rectifier 4 x 12 Partial Review
Background: I recently received my new 4 x 12 Mesa Rectifier Cab from Sweetwater. I bought the Mesa as an upgrade from my beloved EHV 2 x 12 cab. I was able to perform a side by side comparison between the two cabs and the difference (to me) was pretty dramatic. A great advantage of this comparison/test of mine is that it was conducted where I normally play at home - not in a crowded, noisy showroom. Please note that this review is only my opinion, so I'll let you know up front that I'm not an expert by any means and consider myself as a marginal guitar player. I did not utilize any testing instruments such as a spectrum analyzer, dB meter, etc... This is only a partial review. I'm not addressing other things such as costs, construction/specs, etc... What this comparison does address is my perception of the tonal quality for two very different cabs.

The Setup: I used an EVH EL34 100W amp to drive each of the cabs. The guitar I used was a Telecaster Modern Player Plus (great guitar). The two cabs were hooked up in the same room and I stood the same distance from each cab (about 10 ft away) during the two separate tests. The amp and guitar settings were not changed for both tests, with the exception of the amp impedance settings being changed from 16 ohms for the EVH to 8 ohms for the Mesa.

Please trust me when I say that I loved my EVH 2 x 12 cab. It is great for what it is and really, it's probably unfair to compare it to a 4 x 12 cab. But, as I said, I bought the 4 x 12 as an upgrade and it seemed only right to compare the two cabs to help justify my outlay of cash for the new Mesa.

The Test: (Note: I know some of you skipped directly down to this part - you know who you are!) I believe that the construction differences of the internal volume for the two cabs made a marked difference in the enhanced low-end frequencies for the Mesa cab. No, I don't have any great terms to use to describe the low end improvement. All I can say is that it was very easily noticed. Also noticed during the test, the upper treble frequencies seemed to be enhanced from the Mesa as well. However, this could be due to the Mesa's upper two woofers firing in an upward fashion. (From what I understand, the upper frequencies are far more directional than the lower frequencies.)

I apologize that this comparison was not more, but take it for what it's worth. I'm very satisfied with the new Mesa and it seems to be well worth the money!

It's hard to imagine a more quintessentially modern guitar amplifier than a Mesa/Boogie, and when Sweetwater guitarists want high-gain tone, Mesa is where they start. One thing we love about these amps is their sheer versatility, such as the massive range of tone you get from each channel, the freedom to use the tubes you love, onboard CabClone cabinet emulation, and MIDI control. And it's not just guitar amps - Mesa/Boogie's bass amps and pedals are equally cool. What's more, thanks to our incredibly close relationship with Mesa, you can even customize your own amp right here on Sweetwater's website! Get the sound and style you want from your next amp, with a Mesa/Boogie from Sweetwater.
