The Twintone II has all the goodies from the original but Koch managed to add some extra stuff to this small TONE MACHINE.

# We have added a boost on the Overdrive channel giving it basically three channels.
# The FX loop can be used Serial or Parallel.
# The reverb can be switched on/off
# We have included a 5-Way footswitch for channel switching, reverb on/of and Solo/Rhythm function.
# The channel switch has been placed on the front for easy switching when the footswitch is not on hand.
# The front panel has been slightly changed to give it a more modern look.

POWER AMP:
Two EL34´s in combination with a high quality output transformer build to vintage specs, provides an excellent sounding classic power station.
CLEAN CHANNEL:
This is "classic" channel, standard in all models, it´s warm, sparkling and full of tone combined with a superior headroom. It´s the channel where it all starts.

POST-EQ OVERDRIVE / HIGH GAIN CHANNEL
This amazingly flexible channel allows you to create tones ranging from compressed clean, to raw crunch and even to mega-distortion. The specially designed 'Dual-Drive' control provides this enormous range of tones by controling the gain of two pre amp stages simultaneously. Accurate voicing in the pre amp stages in combination withclassic post-distortion tone control enables this channel to produce the right sound in every gain setting.

SERIAL EFFECTS LOOP
This loop, including buffered in- and outputs, operates at -10dBV signal level and therefore allowing you to use any effect unit you want, from an antique stomp box to a professional 19 inch rack unit.

HEADPHONE AND RECORDING OUTPUTS
Special designed speaker-simulating filters ensure that the sound is identical to the sound coming from the speaker.

AUTO POWER-SOAK
This built-in 50W speaker replacer is at your disposal 24 hours a day! Even in the middle of the night it allows you to play the solo you have just been dreaming of with full tube-power without waking up anyone! Just pull the speaker plug (the power soak now connects automatically) and the amp can be driven at full power without any danger of damaging vital parts. You can also use the power-soak as a "second" speaker and reduce the power to 25W.

SPRING REVERB
The built-in original spring reverb tank causes the amp to expand with a great range of vintage reverb textures.

This is what international press wrote about KOCH TWINTONE:Fachblatt, September 1996:
"Clean-channel makes first impression up to it´s name. Up to volume 7 Twintone stays clean and tone is very beatiful and warm. Tonecontrols work very fine and precise like on Fender-Bassman or Plexi-Marshalli. That tells a lot about the tonal qualities of the amp: Fender meets Plexi-Marshall - That's it. If you turn up the clean-channel you get a fullbodied crunch-sound. With Strat it sounds Texas blues à la SRV, with Les Paul and ES more like AC/DC "Balls to the Walls". Impressive! Reverb is beyond all my expectations. It´s among the best comboreverbs I have ever heard.""Oh boy, now we are talking (overdrive channel). With Gain-pot you get lots of power and distortion. At lower third sound is delicious thick "Tubescreamer" sound. Pure rock'n roll. Turn more and you get a really good fat lead tone. I liked the distortion very much, because even with strong distortion the amps tone stayed focused and audible. The work with gain, tonecontrols, power amp and speaker worked very well. Everything fit perfectly. Twintone suits very well to studio, but you can also rock the roof with it.""The tone of this small combo is a true discovery. I don´t know any amp in this pricerange that could compete with Twintone. The Power soak- feature makes this amp even stonger. This is my favourite feature, at 25 watt this amp is loud enough and exceptionally warm.""Dolf Kochs Twintone-combo, that is also available as a head, is really impressive. You can see this amps as a best in it´s pricerange. You get warm and fat Vintage tones, topclass workmanship, carefully made funktions like rhythm/soolo switch and first class reverb. "

Workshop, March, 1997 (Swiss magazine):
"Without distortion Koch sounds very balanced and warm, also when played with low volume. Guitar sounds very rich and mellow. But with distortion little Koch shows it´s power!! From tearing blues true fusion to heavy-metal the whole spectrum is available. ""I can say that little Koch was more powerful I expected. Also when played loud - and Koch does it with ease- Twintone made it 100% . Clean-tone is as I wrote very warm, complex and fullbodied. Distortion is beautiful, singing and has lot´s of upper harmonics.""Great thing about Koch is the foot switchable volume-control. That makes the mp work like it´s four channel. When the volume is set low with footswitch, the tone remains clean and full of expression, only has that much less volume as adjusted.""Twintone is convincing tubecombo, that has impressive tones. You can get all kinds of tones from county to jazz. Successful funktions like the rhythm / solo switch and speaker- and recording-outputs makes it very appealing amp, that also makes it in large arenas. "

Guitar Magazine :
" This is a beautiful made all-valve amp full of classic sounds. The Twintone looks distinctive too, displaying a stylish, retro vibe without obviously copying any one brand or model. And there are some interesting extras...""The drive acts simultaneously on two amp stages, taking you from compressed clean to high gain sustain without muddiness.""The KOCH offers lovely ringing clean tones with rich, untemperamental reverb of generous depth. As per the Fender, the balance between definition and character is most satisfying, although here things stay clean much further up the volume scale, giving a very solid rhythm/clean-lead sound.""There´s no shortage of attact or dynamics, and this channel genuinely supports a wide range of clean styles. A semi-solid sounds as solid as a rock, with fine sustain and excellent tone, and you can add body and warmth to a Strat without losing definition. And thegenerous scale means you won´t need to apologise for ´only´ having singlecoils.""A full channel volume, you´ll get biting and slightly blurry EL34 distortion (great for tough blues if your ears/studio/audience can take it)""Moving to overdrive, low drive settings at decent volume give nice sustain with only slight distortion. By 11 o´clock on drive control there´s dynamic vintagestyle crunch (turning down nicely from guitar, retaining excellent tone) and at higher volume the amp offers great percussive ´chunk` for a 1x12"." "By 3 o´clock there´s singing sustain and lots controllable, harmonically rich distortion on top of a good basic guitar sound. Textbook stuff! Again, single-coil users need not fear embarrassment.""Loud, the distortion channel gives good tone across the range: 12 o´clock on the drive control means a super-bluesy neck pickup sound, whilst high gain volume + full drive really rocks.""Despite the model name, you can expect a great deal more than two tones from this package.""The KOCH is an fine all-rounder, delivering authentic guitar sounds in each depertment from the ´50s to the ´90s. Its clean sounds are solid and well defined, the reverb´s deep and classy, the crunch tones are exciting, and at the high-gain end, this amp is ready to RAWK. It´s solidly built and nicely finished, and includes usefull performance/recording-orientated extras."
