Ibanez TN120 Thermion Head

You can find the features with little effort. 4 12AX7, 4 6L6 Ruby's. Not a bad choice. 120w, 2 channels, hi-low input, dampening switch and FX loop. All tube tone beast. Master Volume for both channels would be nice, but the Effects loop works unbelievably well as a sort of attenuator. I would have liked to have seen 2-separate Hot channels.
Oh and it looks badass.

Rich thick sound with cutting mids. Responds nicely to the character of your guitar and will make ****** guitars sound like ****, but your nice ones sound like gold. I used to prefer the scooped low-mid monster growl from a Marshall to anything, but this thing ebbs more toward that biting Rectifier sound. When I first bought this amp I was using it with the dirt-cheap 8ohm MG cab with low end Celestions. The sound quality was surprisingly good (reinforcing my suspicion that the MG head was total crap) However, the bass response on the Thermion is just plain evil, and it caused this straight-cab to fart out when playing anything low end. After upgrading to a 16 ohm Carvin legacy slant cab with the ever-popular V30s, I began to see what this amp was made of. It's very versatile, but the distortion will quickly become way too dirty. I usually find a sweet spot around 1 o'clock on the gain and somewhere near 2-3 o'clock on the master. Bass around 9 o'clock and the mid's boosted (holy crap!) a pinch. Treble is all relative to what I'm playing at the time. And the presence knob has a nice even response. I think the range on the tonal knobs is amazing. Dampening switch adds even more range to your live sound. Nothing like palm muting on red and then slapping it to green to make your solo shine. I wish it were a separate channel, though, since the gain sounds better at different positions depending on whether or not you have your dampener on. The 1-2 o'clock position is a nice compromise. I'm in love with the vintage clean channel. So crisp, and when the gain is boosted, you can get the most cutting AC/DC'ish rock sound around. When I was in the market for a tube amp I demo'd several ones in the 1k-ish price range, including the Bogner alchemist, a peavey, the Spider valve amps. This one stood out to me mostly because it doesn't sound quite like any amp out there. Some would say this is its downfall. But I'd say its what makes this thing my choice amp.

It was quite funny reading one of the previous reviews. Forgetting to hook up the speaker lead resulted in a blown fuse, but the supplied spare fuse and easy replacement made me happy. And definitely watch your step around your input cable... looks like I'm gonna be soldering a new input jack in.
Other than not being clutz-proof, this thing seems to be built solid. Weighs 50 lbs and the plentiful vents assures your tubes will cook only like they're supposed to, and not overheat. Three carrying handles for reliable grip and metal corners. What more do you need?
Not much circuitry to go wrong in a straightforward amp like this one. Seems to be well assembled.

Well they answered the phone, but I was told to find a electronic repair shop or mail the 50lb beast for warranty when I asked the tech to tell me where the fuse compartment was. After getting off the phone, I noticed the compartment in the connector for the power cord. Spare fuse included.

Tech wasn't much help.

I wouldn't call myself an expert on tube amps, but I do know good sound when I hear it, and in my opinion, this amp has it. It takes a little tweaking, but this amp is very versatile given its simplicity. At $600 delivered it was a flippin steal.

I think this amp may develop a small following, if only for its unique and evil sound. Great for metal/hard rock. I play in a prog-rock/metal band and it gets the job done.

I got a chance to try out one of these amps, as a "Demo" at our last gig. The music store loaned it to us to try out, hopping we'd buy it. 2 Channels, clean and OD, switchable. Lots of control knobs to turn and more features than I'll even need, some usless to me. FX loop, but I never use them, I go direct into the amp. Comes with Ruby 6L6's which are well built tubes, I have them in 2 of my regular gig amps, both are vintage Fender combos. You can switch power tube types if you want from 6L6's to 6550's, just be sure to have the switch in the right place for the tubes your using, it's a "no brainer" tube swap. No need to stress out about rebiasing it, the amp does it automatically. THe electricts are PCB mounted and seems well made, except the preamp tube sockets.

Not bad, but not my cup of Tea.

I like a sweeter Fender sound and this amp and cab just doesn't do it for me. This amp is LOUD! The clean channel on this amp I liked beter than the OD but I prefer my pedal presets and found running them in the clean channel better for getting my sound with my pedals, than the OD channel.

No idea, I think it's made in china.

No idea. It has a standard warantee for repairs. The downside is it takes a long time to get things shipped and repaired, so I hope if you buy one of these you never have any problems.

I woudn't buy it. Not that it's a bad amp, it's okay. I think it's better than some of the other heads I've tried. It just doesn't seem worth the money. I would be embarrassed to tell you I paid $1100 for this head when I can find Marshall, Orange and Mesa heads for close to the same price as this import. I'm sure I'll get flamed for this but $1100 is a lot of money for an import amp.

Too many feature to mention. The main thing I liked about this amp was the ability to switch between power tubes with just the flip of a switch. Nice. It comes with Ruby 6L6GCMSTR tubes which are well made and have a nice warm tone. For the gain guys you can swap the 6L6's for higher power 6550's. No need to rebias, its all done in tha amp, you can fine tune the bias right from the amp if you want to but there is no reason buy a Bias Right or other bias tool, just use your VOM. The thing is heavy and packing it and a speaker cab up a flight of stairs will be a chore.

Played it through a Marshall 4-12 cab and a vintage Fender Shoman cab w/2-15's with a A/B switch to compair speaker cabs. For all the controls and channel switching it's not as good as I thought, sure it does Metal well and maybe Blues or Hard Rock but straight on Rock or Country, not so good. Forget Jazz, it won't cut it. If you play a variety of styles of music this amp ain't for you.

I doubt I'll have it long enough to worry about that.

I hope you can speak Chinese.

I wouldn't buy this amp again, I mean there are better amps for the same money some are even made in the USA. I'll get something more profesional. This isn't a serious amp for serious musicians it's kind of over kill with poor tone.

If your into Metal or Punk and don't really play guitar for a living but like garage bands groupies and large stacks to male you look cool buy this amp and 4-12 cab and you'll be happy.

Nothing too special here i guess, but the "normal, bright and brighter" switch can really make my telecaster cut through in a peircing manner.

A very versatile amp with its own unique tone, i would say somewhere between a jcm to a rectifier, As stated i use a telecaster MIM and a epi 56 goldtop with p90's, mostly i play a sort of rock punk sound and this amp fits it with style, plenty of gain for me but i rarely need to go to 10 on the dirty chan. Do not buy this amp as a substitute for a particular sound, with pedals it could be achieved but it has its own unique character.

Very very sturdy, have owned it for about a year now and only done a fuse, the input jack can be a little weak if you stand on your lead (my bad) but overall a very solid reliable unit.

Ibanez's only problem for me is sourcing parts to australia, "bloody input jack" but they didnt dick me around too much.

Overall a damn good amp for a fresh and unique, heavy vintage sound. Would recommend to just about any musician as it is very versatile and quite sublime. In time will buy another head for backup and or crazy volume, ibanez's only A class amp.

This is a brand-new all-tube head from the good folks at Ibanez. I am going to be honest: I have only tried the amp a few times and currently do not own it. Not yet anyway.

This is 120-watts, all-tube, and it has two channels: Vintage Clean and Hot. The Clean has a 3-position "pre-eq" switch to change the brightness and top end. The Hot has two functions: a retro-ish crunch and a fatter recto-sounding metal tone. The head is 54 pounds and it relatively light for a tube head. It's also built like a Sherman tank!

The effects loop is unique in that, you can use it as a boost for solos, even if there are no effects plugged into it. But the secret weapon it the toroidal transformer in the head itself. You can play this thing LOUD and not worry about noise. It's not 100% quiet but believe me, you'd miss it if it weren't there.

So far I have only tried this amp in my music store.

This amp is finicky! Certain pickups sound amazing through this head. Duncans and EMGs SCREAM!! DiMarzios tend to fart out a little. Of course, don't even bother playing single coils through this, it sounds weak and thin, even in the clean setting.

I've played all my 7-strings through it and the two w/the Duncans were scorching!! The Universe guitar sounded good w/the DiMarzios but tended to dump on the lower B and E strings. And here's another trick: the Thermion cabs squash the high end, so if you're a speed-picking soloist, those notes will get lost in the sauce. As crazy as this sounds, the Tone Blaster cabinets sound better with this head. Yeah, you don't get the 3D sound that the Thermion cab offers but you will hear your notes a lot sharper.

The clean channel is alright, not quite as resonant as a Fender or even the JSX head but it's not the 5150, that's for sure! The "green" channel on the distortion is okay if you're playing Zeppelin-style rock (which I love, of course!) but really doesn't jump out at you. But the "red" metal sound is KILLER!!! Tweak it just right and the hairs on your arms will stand at attention!! This setting is perfect for down-tuned or 7-string heaviness.

And yet it's virtually noise-free, even at a blistering volume!

It's built very solid and it's lighter than average for a tube head.

Haven't tried it in a live setting, so I'll have to get back on that.

Customer service is great. Again, can't comment right away since this head is still new.

After playing it a handful of times, I can truly say that this head is well-equipped and ready for action. It's not an amp that you can just plug into and expect god-like tones; you really have to tweak it for a bit.

I've owned the Peavey 5150 and JSX heads over the years. I'm very touchy with tube heads. I honestly prefer solid-state, for its consistency and reliability. To be fair, for the right price, I would consider playing this Thermion head. If I do get it, I may switch the tubes out. Not crazy about Ruby tubes. Maybe I'd use Groove Tubes. Who knows?

I played this amp in a DJM store. The staff had been shown the prototype by the Ibanez guys months ago. We were all VERY critical with the amp... at first. For me, Ibanez makes great basses and good drum sets(Tama). However, their amps and guitars have always SUCKED. I mean "Horny-Vacuum-Cleaner-Suck"! I've been on the search for a great tube amp for years. I've tried Peavey Classics, JCM 800, JCM 900, Mesa Dual-Rects, and more. This amp is insane.

I tried a Gibson SG, and Gibson LP Custom with it. The LP sounded 5X better(balls).

First, DON'T USE THE THERMION CABS!!! The cabs squeezes some of the balls out of this amp. It sounds much better on the cheaper Ibanez Tone Blaster cab($300US). Hard to believe, but try it... I have yet to try it on my Marshall 1960A, but I would imagine it to be a much better match, than the Thermion.

Ibanez says 2... But, this amp is a 3 channel amp. It's got a Vintage/Clean and a Hot channel. The Clean is VERY versitile and sounds great. The Hot can sound just like a Mesa. If you turn the gain down and crank the mids, it's a JCM 800. But, this amp's secret weapon is the EFFECTS LOOP!!!. The loop has another TUBE gain-stage. You don't even have to plug any pedals in. The "Send" adds another set of balls to the amp, while the "Return" either adds or subtracts to the Master Volume. That is why I call this a 3 channel amp. The Effects Loop is essentially a seperate Lead Channel. SWEET!

I love this amp, but I don't think the sound it makes is perfect. It's definately worth $1100US. I would pay 1600 for it... Probably more. But, it's not the prefect amp. But it's much better than anything I've played thru before. I'm gonna say 10, but it's really a 9.4

To give you an idea of my taste:
Slash's sound is a 9.8
My JCM 800 is a 7.6
My JCM 900 is a 2.1
Peavey Classic is a 4.5
Mesa Dual Rec is a 6.3

I don't know. It JUST came out a week ago...

I played this amp at The Only Guitar Shop in Clifton Park, NY on RT.9.

I am not going to get into all the little control features like all the knobs and such -it is already listed on the specs list. I will, however, tell about the sound I got out of it & that is my main focus for this review -To let you know what I thought about it and what to expect from this amp and no matter what I say it is still MORE then worth going out of your way to hear it!

Channel 1 is the clean channel & there is a knob for setting it's brightness and 2 different distortions in the second channel of the amp: Dist 1:Classic rock & dist 2:BONE CRUNCHING WHOLLY MAMMOTH DISTORTION. A hi/lo switch at the input jack. I guess these are the features that stood out to me and with 3 clean sound and 2 dirties I guess that is what is supposed to make it versatile.

This head is made for heavy metal of all types and classic/hard rock. However, you use the same low/mid/high settings for both gain stages.

At any rate, Onward...

I give it a 9 because I didn't think the sounds measured upto what they were made for I don't mean this in a negative way -I will get into this under 'sounds'(ok... Honesty is the best policy, I hated the classic rock distortion)

I played about 5 different guitars through this thing: Paul Gilbert model Ibanez (sounded very good), an ibanez SA 320 (sounded muddy not clear at all), ESP M107 7-string (muddy, sludgy, retains some power chord note value but no clarity when riffing), a Squier fender fat strat with 2 Seymour Duncan humbuckers (sounded weak believe it or not) and a fender USA fat strat with a maple fret board- sounded amazing!

It is a very quiet amp no hissing or humming. It feedbacks well. The one thing I really loved is that the tone controls really have a wide sweep in them. Every setting between 0 to 10 is adding lows/mids/highs/ or taking away going 10-0. Unlike on almost any other tube amp going from 0-10 on the tone controls is like going from 0 to .5 -there is almost no change in tone. However, not the case with this. Tweaking the controls really bring out the sonic possibilities in this head. 'A la' The Boss Metal Zone pedal?

The clean channel is 'so-so' not much to say about it The brightness switch really adds flavor to it though.

This distortion is absolutely insane! There are metric tons of God's Wrath in this 120 watt head! It seethes from this head. It has a little more distortion then the Mesa Recto & about 1/3 more then the Bogner Uberschall has! Marshall cannot even compete with this & I won't compare it to anything else because I think this amp is of boutique quality and is far superior to Peavey, Crate or anyone else who has made heavy metal tube heads before. But, to be fair, I have not heard a Framus or a Peters or many other small tube amp making boutique shops which I hear make amazing tube metal heads.

Now, the nuances I felt worked against the whole idea of what the head is supposed to be used for.

The distortion & tone is in my opinion a cross between the 'tone' of a Fender Hot Rod Deville -smooth & tight- with more sweep in the controls and the distortion of the Mesaboogy -massive death & destruction of biblical proportions. That is to say, it almost sounds like a really pissed off blues amp gone nuclear. But, it is a metal sound & I bet 99% of people (which will be millions) will love it. However, for the rest of us 1%'ers out there, we listen past the death and destruction of the distortion and know that its a massively overdriven blues tone and is too squeegy & smooth to be a true metal sound. Also, the bass is awefully muddy and while riffing the notes tended to fall apart -A la Nevermore, Pantera, Megadeth, Lamb of God, God Forbid... You know? And Playing power chords is too muddy sounding in my opinion. But, maybe that is due to the Ibanez Cabinet speakers? -Celestion? Vintage 30* speakers. High notes are really full and sing with this rounded chimming warmth and smoothness -you want to hold a bend forever because it sounds so good. When picking the high notes you can hear that pick attack sound. Not so with the low notes it kind of falls apart. I even turned the bass all the way down but then it sounded to thin and gets muddy fast turning it up. I think it has an inherent paradox in that it is too metal for blues and too bluesy for metal. Come to think of it, a perfect description is Eddie's 'Brown sound' with tons more distortion and 'I DO NOT MEAN THE PEAVEY 5150 head AT ALL'. I DO mean the kickass marshall he used on the first Van Halen album.

The classic rock distortion is a joke. I can't understand how ibanez didn't hear this in the lab. It's too glassy sounding with no balls and its real thin and there are no harmonics to be heard. I could not pull off a Zakk squawk for anything... I don't know. Maybe it is good for 60's rock 'A la' Cream, Zepplin?

Over all the amp is metal but it sounds like it wants to be blues and
maybe changing the tubes would take away some of that 'squeeginess and smoothness? Hmmm...

Let me state this before I end this review: This amp does sound incredibly fantastic and it is totally more then worth you going totally out of your way to hear it! But, as I stated, I do have some issues with it.

When was the last time an ibanez anything broke? Actually their low line shit is just that -shit-.

Their high line products are amazing.

I would use this thing to build a skyscraper on! It looks rock solid!
But, I can't give it a review catagory rating because I have had no experience with it...
