Genz Benz G-Flex 412 Cabinet

Two 4 ohm stereo inputs, one 8 ohm mono.. enough to cover most situations. the ported design isn't just for show.. as others have noted, they have a pronounced effect on lows and low mids. this cab has punch for days.

I've had this cabinet for a long time, and it has been so good to me that i almost felt i owed it to the manufacturer to add my praise. you'll rarely find a cabinet that articulates like this one, especially the "soulful" solid mids and lows. the highs aren't harsh or overly bright, but if you're playing a brighter-than-average sounding amp through it there isn't any squashed tone. a lot of thought and effort went into this amps design in terms of sound quality vs. appearance or cost effectiveness, which is more than can be said for a lot of major enclosure manufacturers, and this is evident when you play through it.

I've had this cabinet and the genz benz el diablo 100 head for about 6 years now, and the only problem i've ever had was a blown fuse (in the head) from a lightning strike. never a single problem with the cabinet: it is at least as reliable as any other high end cab.

i've never actually had to have customer support for the cabinet, but once when i was retubing the head i thoughtlessly disconnected the positive and negative cables that connect the reverb coil so i could remove the entire back plate, and then i couldn't remember which one went in which side. i sent an e mail to genz benz's customer service address from their site, and low and behold about 3 hours later jeff genzler himself replied very warmly with the instructions! total class. i wouldn't expect any less if it was an enclosure issue.

this cab might not be right for everyone, but it could be great for anyone. if you're in the market for a new cabinet, i suggest at least trying this one out before you make a final decision. i've heard several amps played through this cabinet immediately after having heard the same amp through other cabs, and the tonal quality has yet to be matched by all accounts. great tone, and very versatile.. i use this cabinet mainly for extreme metal and shred, but, like most guitarists, i'm occasionally taken by an urge to play some raunchy blues or jazz licks. i can always get this cabinet to produce a tone to rival that of any dedicated blues or jazz artist. if something ever happened to this cabinet, i wouldn't bother considering anything else.

You know the specs by now.It's perfect!

I play a schecter C-1 XXX with a dimarzio breed and D-sonic neck and bridge,through a Crate BV150H head into this cab straight,no pedals,no processor,and it wails!It's tight,low and high!Mids are excellent.

These cabs are bullet proof.

They are great!

I've been playing 5 years and I've played through many heads and 412 cabs including Mesa,Marshall,Peavey,Crate,and this cab rules all of them,in comparison the most highly touted 412 cabs pale versus this cab,do yourself a favor and check this cab out,it's a sleeper,it's a monster,and then it's as sweet as a newborn baby.I won't play through another again,my band loves it,we will all play the G-Flex now!

4 X 12 with Genz Benz labeled speakers.
I got it as a trade-in for guitars.
Condition was 8.0 out of 10. mostly vinyl damamge to back.

Incredible hoomph! and Thump!
Clean mids and highs.
Actually as good as the top of the line Mesa-Boogie.
Blows any & all Marshalls away!

Worked good. So good that my first serious cusotmer bought it off the sales floor after a 5 minute demo.

Unknown, Great reputation.

Sounded fantaatic! Wish I had one for me, but I don't play rock anymore so it would be a waste of space.
Downside = Heavy weight. Much heavier than my Carvin 4 x 12". Actually too heavy for me to transport safely even with a hand truck. I would have kept it for the sound if it wasn't such a beast to move.

The G-Flex caught my eye a long time ago and I needed a cab to go with the matching El Diablo 100 Head I now own. The cab has 4 ported subwoofers underneath that increase low-end thump and resonance.

Make no mistake about it, this cabinet is HUGE! And I'm not just referring to the size of the thing, (over three feet high with the included casters). The tone is insanely filled with headroom. But it's not just designed for mad thumping low-end stuff. Play clean through it, and it purrs like a kitten. A lot of how the cabinet responds is going to depend a great deal on what guitars, pedals and amp(s) that you run through it.

Yes, I know, that's true for all amps and cabinets. But with this one, there is a drastic change. It all sounds great, but you will notice an immediate difference in tone color, speaker movement pattern and soundscaping just by switching guitars or pedals. It's that important. The biggest factor is how your amp sounds. I run the matching El Diablo head through it and it gives me unparalleled versatility just because of how nice that head is and the way I've got it set up. Like anything, you just have to toy with it.

Haven't owned it that long. But I've heard that Genz Benz has a tremendous customer service reputation, not to mention the fact that I have an authorized dealer right downtown, in case of any problems. Haven't gigged it yet, but once I get to college, you betcha.

Never dealt with them, but again, I hear Jeff Genzler himself answers their phone all the time, and they're very helpful.

Do yourself a favor and buy this cabinet. I've tried tons of them, including a very nice hot-rodded Marshall 1960 with a custom white grille and tan leather job, an incredible Trace Elliot, (God, I wish they still made those), a Mad Sound, which I own, (it's just a little 2x10" cab with only one speaker in it, what they call a "detuned cab," you'd be very surprised how incredibly loud it sounds), Peaveys, Crates, Fenders, and this one tops them all. Every single one.

Don't be deterred by the high price. It is up there in Mesa/Boogie and Bogner range, but it is worth every penny, I promise you! I would trade Eddie Van Halen's original Marshall stack for this sucker.

I've had this cab for a couple of weeks now and at every gig i've done it has performed perfectly. It can handle anything, it's very versitile. However, the wheels that come with this cab are shocking. Therefore I can't give it a 10.

I use a Gibson Explorer Gothic with Seymour Duncan JB and Jazz pickups and an ESP Eclipse with EMG 81/60. I have a couple of pedals (Visual Sound, MXR, Dunlop etc) and an ENGL POWERBALL amp. I did have a Marshall cab in which I upgraded the speakers to celestion vintage 30's and I thought that sounded pretty good. That was until I plugged in the Genz Benz. Wow. Very tight bottom end, smooth mids and the most projection from any cab I've ever herd. It really is fantastic.

I re-valved my POWERBALL with Electro Harmonix tubes ( 4 x 6L6GC and 3 x 12AX7EH and 1 x 5751 in position 4 in the preamp) which has made a big difference. I always knew that the Electro Harmonix valves had better punch and it really shows through with this cab.

Haven't had it long enough to find out about reliability yet. I think I'll invest in better wheels though.

This cab is fantastic. Its better than all the Mesa, Marshall, Bogner, Randall and Engl cabs I've herd. Go and get one!!

Can run it at about any ohm setting. It is very flexable.

This cab sounds amazing. Huge low end and crunch. No farting with this cab! The mids are perfect with a bell-like high end. I run a Krank Revolution through it at 8 ohm mono w/ my Schecter Scorpion Bartone w/ a Dimarzio Super Distortion in the bridge position tuned in drop A. I also use a ESP H-1000 Deluxe with a Seymour Duncan JB at the bridge tuned normal. It sounds fantastic with the head. The only effect I run is a chorus which simplifies things live since I also sing in my metal band.

It has never let me down yet. Sounds great every time.

Never had a problem yet. It seems to be made very well accept for the squeaky crappy wheels on the bottom that drove me insane. I took those off and put it on an amp isolation riser. Wow. It sounds gigantic!

I have been playing for 12 years and this is the best cabinet I have ever had. I had a Peavey Triple XXX cabinet which sounded pretty ok, but not near as good as the genz benz. It is a bit pricey though. Usually around $950.00. You definetly get what you pay for though with this amp.

All the features you could ask for in a speaker cabinet, and just looks so F'n cool.

Best Cabinet I have ever played through. Perfect for any stlyle of music (but best for Metal!! \m/). Very big sound, well defined and tight. Will cut through the mix! Have played through it with a Line6 HD147, a Marshall JCM 900, and a Marshall JCM 800 Zakk Wylde signature. Just outstanding.

Had a problem with the 8 ohm Mono jack. Emailed them and got a reply from Jeff Genzler. After several more e-mails back and forth and reveiwing it with his tech, it was determined that the jack was not closing completely. Since there are no dealers or authorized service centers where I live, he sent me out a replacement jack plate. Replaced the jack in less then 10 minutes and it works perfectly.

I can't emphasize enough how important this type of personal customer service is. It's something that other companies should take a lesson from.

I will never buy another cabinet, period.

This is a follow up after I ran into a problem with the cab. The wire that carries the current to the voice coil in the speaker snapped off at the voice coil, and the speaker was no longer functional. I emailed genz-benz and exchanged a few questions and answers with Jeff Genzler himself before calling him on the phone and fully explaining the situation. I shipped the speaker to genz-benz and they sent me a brand new speaker promptly. A pleasing experience from an unpleasant circumstance.

4x12 cab loaded with custom genz benz 12's, from what I hear they are modeled after vintage 30's. Front ported design w\baffles to spread the sound out. 8 ohm mono, 2 4 ohm stereo inputs, extension out.

I have a Peavey triple xxx head that I was running through a Marshall 1960b cab. The amp sounded awesome through that, but through my g-flex it's like an entirely new amp! This thing sounds amazing, the low-end is tight and pronounced with no woofing. The mids are smooth and it has a real nice high end to it. The clarity I get out of this cab is amazing, I never thought a cab could sound this good. Imho this is the best cab out there.

it's new, but seems to be built like a tank, shouldn't have any issues

I compared this to my Marshall cab obviously, but when I went to the store to get it I also tried out a standard recto 4x12. The recto cab sounded really good, but after playing through the g-flex there was no contest. This is truly the best cab I have ever played through. I highly recommend this cab to anyone.

Stereo or mono operation. I like the casters because you can remove them with no tools. Wire grill cover looks good and is solid. Very nice looking cab, as far as that goes.

This is where it counts, of course, the sound of the cab. In my opinion, this thing has excellent tone. I sold a Peavy 412MS to get this cab, and I wasn't dissapointed. It sounds 10 times as good as the Peavey. Clean tones are lovely and ring like a bell, and crunch tones are powerful and responsive. Simply lovely tone through the entire frequency response. I'll never sell this cab!! I use a Genz Benz El Diablo 100 head with it, and it sounds AWESOME!! I've finally found a rig I'm satisfied with. (it only took 3 years)

No problems.

I emailed Genz Benz with a question and got a quick response from Jeff Genzler himself. I like this kind of customer support!

Been playing for over 10 years. I play a Gibson Les Paul Standard mostly, and occasionally a Strat. Both sound great through this cab. This cab matches the El Diablo head very well. (a GREAT head!) I can't imagine getting any better tone from a half-stack of any brand whatsoever. I love it and plan to keep it.
