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)
2 IN (low / high)
1 Loop in series or parallel; great
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

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
