yoTrakkz's review"Loud"

Koch Twintone II
I Have Used the Koch Twin Tone II, And in a word to describe it is amazing,awesome,powerful, I have used Koch amps in the past but this amp totally blows them away it has the cleanest of clean for jazz and country, and the most awesome overdrive I have ever heard from a amp. I don’t play real hard rock but if I did I know this amp would be awesome and not miss a lick. The pedal is amazing the way you can just set your sound on the amp and it just programs in to the foot switch.


I live in an apartment, and I had the volume at about 3 and my neighbors called the cops, so. I think it would shatter windows at 10. The new Wah effect works really good with the FBV Express pedal, and also makes the amp that much better.


The second i plugged in my guitar it has great tones and presets to choose from. I also love the fact you can plug in your mp3 and jam along with your music. Some neat effects on this amp are auto wah, pitch glide, and volume swell. These effects work best with a foot board which i plan on purchasing soon.


For the price, this is a truly amazing amp. While the preset tones are cool, and good for a playing a few songs, I think they are better defined as great templates or starting points. You may find a tone you like, but just feels to be missing something, just tweak it to your liking. The basic models are great too. Each model offers two settings. Between the models, and all the effects, the possibilities are almost endless. It has your basic line out connection, and you can plug in your cd/mp3 player if you want to play along. It's got the hookup for the footswitch which is a must have addition. All in all, for the price I paid, this amp is top notch

iamqman's review"Not a bad amp"

Koch Twintone II
Koch is a company based out of the Netherlands and has been building great quality amps for musicians around the world. They have a good reputation as a simple guitar amps that are full of tone. These are high gain monster and they aren't sweet innocent clean amps. Koch is somewhere in between with their gain style and voicing structure.

This amp is a 50 watts blues style amp. They don't market it as a blues amp but that is the tone I hear when I hear this amp in action. You can definitely get a decent distortion from it but the voicing is just blues. I don't think it can be dialed out. Not that it is a bad thing just a particular thing.



* 3-Channels: Clean,Overdrive and Overdrive+
* 4x 12AX7 and 2x EL34 tubes
* Serial and/or Parallel FX-loop
* Solo/Rhythm facility (switchable)
* Accutronics spring reverb (switchable)
* Koch VG12-90 speaker (Combo)
* Built in Power Soak (0, 25 or 50 Watts output power)
* Recording output
* Headphones output
* 5-way footswitch included


This is a three channel amp one dedicate to clean and one for the distortion. What is different to this amp is that it has a middle EQ for the clean channel. Most amps I come across and especially Fender has only volume, bass, and treble. There usually isn't a middle control knob for the clean. That is a simple but great features to have.

The distortion is kind of honky to me. I don't really like the tone of it all that much. It sound small and boxy. The tone of the clean is too but not as noticeable as the overdrive channel. The distortion I feel with the OD and OD+ switch just muddies up things. It isn't very pleasant to hear.


I am not sure what the going rate for one of these amps are used. I know that they are around $1800 new. They are great for the clean tone but I wasn't that impressed with the distortion channels. I would recommend this amp to a blues based player and not a hard rock player. It will sound good in a pop or mild rock setting and do fine. To me this amp is just ok.

Koch Twintone II
All lamp 50W (I original ones)

1 headphone; not tested
1 rec output with speaker sim; great
2 HP 4 or 8 ohms: Awesome

3 channels:
1 clear with Bass Middle Treble flights
2 and 3 have more gain and presence

Nice reverb ... or not


Very simple manual cool logic


he does everything
clear and is deadly with my ptite distos in pedal before the preamp c is the foot
The crunch and saturation are very good and have a nice color .pareil with overdrive before deadly c
He can not palm mute the metalheads alone but with more pedal no problem

I love my junior hp jfais out above as blues and it is really good

Rec output is great: direct sound card with a -20 db pad j'met the knob from clean to j'debranche bottom speaker and these are my grates do the rest ...

guiomarno's review (This content has been automatically translated from French)" small but tough"

Koch Twintone II
All Tube Amp-(cf. constructor)
-Two instrument inputs: a normal (single coil) and the other suitable for humbuckers
Three-channels: a clean EQ with two channels and OD OD + with EQ, gain and volume common presence.
Spring-reverb (adjustable rear)
-Power Soak, protects the amp when hp is disconnected.
-Setting the master by the solo button, which allows two volumes
Taking direct out-
Emulation-output speaker
Effects loop-parallel and serial
-Two speaker outputs, main 8ohms (50w), secondary to switch to 4ohms 25w with the same hp, and the ability to connect two HP 4ohms (50w)


-The amp is simple to adjust the equalization is accurate, although its action means the sound by turning the knobs.
-We put some time before finding her, and what a sound!
-The manual is in English. I put 9 because of it.


I used the recovery Twintone in Pop / Rock, piano bar, restaurant and outdoor.
It is very versatile, and I agree with a lot of styles. It is just limited in metal, but I will say that the head and cabinet in 212 or 412 would be better suited to this style. But should be for everything else.
I play Jazz and Rock Prog. It is perfect for my style.

Crystal-clear channel
Od-Channel hot and runny
Canal + Od-straight and precise, powerful and modern. (But limited gain: this is not a high gain amp, cranked the grain become more rough, especially at high volume overdrive and a clean boost in may solve the problem)
He lacks headroom slightly, but it is very small (one hp, normal)
-The reverb is nice and not too intrusive as the little brother Studiotone
He accepts pedals well, both in front and in the effects loop, which is parallel or in series, and has a knob together with the reverb


I use since September 2011.
I tried Studiotone, I have since 2010. (The clean sound is excellent)

I like
Constant-quality sound overall, equal at different volume levels
-Each channel has its own personality
-The ability to play at very low volume

I do not like
Its relatively high-weight (26 pounds: small but tough)
Its-button reverb to the rear, not very practical, too protruding, which also serves as a loop volume effect. It complicates things, but it's not embarrassing in the long term.

Great value for money, professional equipment is easily affordable, durable, and hand assembled in the netherlands.
With experience, for small scenes and piano bar, I would do this choice with your eyes closed.
Composed for my projects, I orienterai closer to the head version + baffle212

Tanergol's review (This content has been automatically translated from French)" Clean that slaps!"

Koch Twintone II
tube combo - 50 watts, 1x Koch VG12-90 speakers, 3 channels (clean, drive and gain), 4x 12AX7 pre-amp and 2x EL34 power tubes, reverb (output 0/25/50watts) , headphone output, includes a 5-button pedal, line out, FX loop, taken to other HP, etc. .... Weight: 26.5 kg.


the manual and easy, with example configurations (Clean, Jazz, Heavy ...)
But then the configuration of the amp is very simple.
The sound is there, I play with a JEM 7v (so DiMarzio Evolution).


The clean sound is really incredible, the sound "Tender Surender" is at your fingertips!
for blues / jazz need anything else, the rock / a little heavy it out.

For some sounds, I think especially "Heavy Metal", a good effects pedal can sublimate the craft.

But again the sound is really great lens, DO is not playing with the volume to go from crunch to clear.

Each of the guitar pickups can be expressed and you really feel the difference.

It's all good.


I have this amp for now. I tried a lot of things, I tested also very good Studiotone XL, virtually the same sound settings with more than it seemed.

I had for quite some time a Fender Vibro-Champ Lampsa in the 70's. With my dual humbuckers impossible to arrive at a clear worthy of the name, it always Crunchant.

Otherwise a 100 watt marshall, I'm happy to put aside.

The price is downright affordable compared to the amps, Mesa Boogie type US imports, the price is 50% cheaper than a Mark V, for example.

I would do without this choice problem.

jeanclaudeduss's review (This content has been automatically translated from French)" top"

Koch Twintone II
any special light show on their sites
50 w connection could not be more complete


you plug the sound you got
sturdy, well finished
Precision 50w is more than enough for repeated concerts etc. ... do not rely on the value declared but even at low volume the sound was


jazz to metal to blues rock fusion can do everything


5 years, super reliable you understand love
really trying
I quibble to be credible

- Weight
- OTS function on this supernova I'd like to have there!

wdom's review (This content has been automatically translated from French)" !!!!!!!!!!"

Koch Twintone II
The good "old" sound of the big Mesa Boogie as they did more.
Solid, complete with an excellent spring reverb. (Not digital stuff)
Worth a guitar to the pitch to deliver its quintessence.
Usable in any volume in his room at night without frustration the next day during the repeated medium power and becomes a stage animal who will not fail and gives its full potential on stage thanks to its peak output level, adjustable and quality manufacturing, now become exceptional.
Such an amplifier, once acquired, is careful to life!


Can hardly be easier!
The manual will be consulted as to replace the lamps.
The right sound, we do not seek, and it is there, then everything will depend on the choice of the guitar!


Rather the sound is typed Metal: Modern! ... Like any really good equipment, it is very versatile.
Again, sounds will rely entirely on what you put in front (Guitar & pedals)
With my Jackson Dinky Hand Made USA; body basswood, maple neck ebony fingerboard, Ernie Ball Strings, EMG Pickups, the sound is clear slamming, powerful with great harmonics and Disto, powerful, full-bodied, a deep bass, a rich medium that allows good control and variety to the game so very expressive.


Used for 3 years, every day with a constantly renewed pleasure.
I started with a Roland Micro Cube (I recommend!), Tried a Fender tube not convincing at all, I had a Vox know what to finish with a Vox AD60VT combo digital effects that I really liked about first time and which I soon tired (digital effects; year's good start to define what we want really)
This is a truly exceptional amp for which the concept of money does not really make sense ... If there is one, is for life! What amp

olboy1948's review (This content has been automatically translated from French)

Koch Twintone II
All tube, 50 watts power tearing (I could never grow beyond the volume of 4), classical connection


super simple settings, I have not yet managed to get a bad sound.
Manual in English, but clear enough


I play in a group of rhythm n 'blues with this amp and I get all the sounds I need.
I use a Gibson Les Paul Standard, a Fender Start U.S., and a Fender Jaguar.
The clean sounds are very clear, and crunches and saturated, are quite suited to my style of music.


I regularly use this amp for two years only in concert. He did not create any worries.
I do not know Koch, and I wanted to replace a Fender Hot Rod Deville due to his weight, my idea was to take a Hot Rod Deluxe much less cumbersome. My dealer lent me a Twintone II to a concert (the best way to try) and I kept it!
I think the value price of this amp is quite correct.
I will not hesitate to make the same choice

Éric's review (This content has been automatically translated from French)

Koch Twintone II
- What kind of amplification (lamp, transistor ,...)?
All lamps Lamps

- What is the power delivered?
50 watts warm

- What connection?
Comprehensive for the range (see below)

- What are the settings, the effects? ...
Settings usually very effective (it changes dramatically with its equal).
The reverb is very nice

When it works ...


- The configuration is it simple?

- Gets it easy to sound good?
Is to get a bad sound to be complicated.

- The manual is clear and sufficient? ...
In English, but very clear.

When it works it can be used ...


- Will it fit your style of music?
At the beginning I have a little trouble because I was accustomed to the Vox special and it took time to adapt.
But when it works, so it suits me.

- With what (s) guitar (s) / low (s) or effect (s) do you play?
Rikenbacker 330, Gibson Les Paul, Fender Telecaster, Fender Jazzmaster.

- What kind of sound you get and with what settings ("crystalline", "bold ",....)?
Its clear then there hats off to Koch's sublime, the crunch is good too but I like Orange or Bogner (but not the same budjet)

- What are the sounds you prefer, you hate?
I prefer when it works, I hate it when it is silent and down! grrr


- How long have you use it?
1 month, and returned 5 X SAV

- What is so special that you like the least?

- Have you tried many other models before buying it?
yes, a lot.

- How would you rate the quality / price?
If it is not reliable, well ... 0 points!

- With experience, you do again this choice? ...
No, bad experience.
The shop I took it back and bought one instead Studiotone whose design seems more reliable.
I had 5 outages over in 1 month. (Luckily it was guaranteed). The last repair was a total reconditioning of the amp with the new parts of Koch.

The store ended up not understanding me back what to do!

The repairer of the mag. confirmed before the boss that many Twintone had serious manufacturing problems that he was exhausted to see them all the time back in SAV.

What a few shots before my son face to three French distributors of the brand, I heard with my ears (as in hp) that redistributors had the same problems on Twintone.

I could not believe my ears.

He then contacted the importer Koch who confirmed they had trouble with a series of Koch Twintone (which series?).
It was enough that the receiver returns to its cost to the parent to eradicate this problem.

He made me an exchange with a Studiotone that IT works for now well and gave me a refund of the difference and 60? for 5 round trips to repair the other.

So, now who wants to understand (can)
I got rid of the ball amp.

electroJul's review (This content has been automatically translated from French)

Koch Twintone II
Class A all-tube amp (12AX7 & EL34).
3 Channels.
Power attenuator.
Reverb Accutronix.


French manual. Easy to use, settings (EQ, etc.) purposes.


Style I play Rock / Blues. The clean this amp is comparable to the famous Fender amp (I compared with HotRod Deluxe: Really nothing to envy). Distorted sounds ranging from vintage to modern (and channels OD OD +). SUPER VERSATILE! The sounds are very rich in harmonics (lamps) it either clean or saturated.
Satu rich and crystal.


I hesitated before my purchase after reading the post of arsaniit. But I asked my dealer to confirm Lyon who also called the importer to confirm the words of arsaniit and it turns out he has not had a pot (as can happen with any manufacturer). The importer has confirmed that some models have had little problems There's a few times but he assured us that the problems were being extremely rare today.
I therefore find the quality / price excellent. It's been two months that I have mine and ... This is great! The animal may be a bit heavy but the lamp thus implied.

I would do without hesitation that choice (or may be hesitant with Studiotone XL).
