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 features Solo/Rhythm facility, Switchable Speaker Damping, Classic long-scale Accutronics Reverb. This is a tone monster amp and the big brother to the multi channel twintone amps. These are a little big more featured as far as versatility and options. There is a lot more this amp can do over the twintone.

Fantastic from front to back top to bottom. 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. So this makes the clean ton of this amp much more versatile to your guitar's needs and playing style.
The distortion is much more heavy that the twintone. I like and prefer the voicing of this amp over the smaller brother twintone. This one steps outside of the confines of the blues style amps and gets more in the rock arena.
At new these amps come in at around $3300, which is a big kick to the groin. That is a hefty price for an amp like this. I don;t feel that it constitutes that kind of price point not matter how well these things are built. I wouldn't recommend for that kind of money. If I were going to spend that I would get a Bogner for that price and be able to service it a lot easier if anything should ever happen to it.
