Koch

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 is one of the most impressive amps that I have come across in some time. Just by the look of it you wouldn't think it has all the features is does but once you get a chance to dig in you find out how much this amp can do. This is one fantastic sounding and performing studio amplifier. UTILIZATION Specifications Koch Studiotone Amplifier * two EL84 power tubes * 20 watts * Clean, Overdrive & Overdrive Boost channels * passive Bass, Mid, Treble controls * mid shift (2-way) and bright (3-way) controls * new single 12" VG12-60 Koch speaker * 4, 8 & 10 ohm speaker outputs * speaker on/off switch * built in power soak * line output * recording output with speaker simulation * headphone output * effects loop * Accutronics spring reverb * 2-button footswitch * 17" wide x 9"deep x 16 1/2" high * 33 pounds SOUNDS One thing that I really like on this amp is the the id shift controls. This allows you to dial in the right amount of midrage that fits your playing style and guitars. This is very important features because the mids a lot of times can either make or break an amp. You wouldn't be able to jive with an amp that has crazy weird mids or none at all. Since the mids might be the most important frequencies for recording this is a solid option to have in a studio amplifier. Another great feature is the power soak. This allows you to get a good distortion tone and gets that wattage down to a tolerable level for recording or just being in the same room together. Along it the ability of the line out put for direct recording into the session or even going right into the house PA system. This is a fantastic amp and great for the studio. OVERALL OPINION At new these amps come in right at around $1750. not a bad price for a high quality studio and recording amp. This amp has is all when needing to record with it. I highly recommend this amp to someone who needs good recording amp that has three channels and a great clean tone. This amp has it all for recording and studio use.

The Twintone is the bigger brother to the studiotone. 2 full independent channels with their own EQs and El34 power tubes as opposed to EL84s. Tonewise, a change and more versatility feature-wise. High and Low inputs 50 watts at 8 or 4 ohms 2 channel preamp, footswitch selectable Classic clean channel Post EQ overdrive channel with four gain stages Dual-Drive control Four 12ax7 preamp and two EL34 power amp tubes Buffered effects loop DC coupled, serial signal level -10dBV Solo/rhythm volume, footswitch selectable Auto power soak Headphones & recording outputs Speaker simulating filter, passive 12dB/oct. Accutronics classic model reverb One 12" Koch VG12-90 speaker 2 speaker outputs, switchable 4 or 8 ohms 2-way footswitch included with LEDs Option: Head version Dimensions (cm) combo: 50w x 47h x 28d - head : 50w x 28h x 28d Weight Combo: 23kg - head : 14kg UTILIZATION Again, very simple to use, laid like a regular amp. There's also the DI recording out which is useful (but doesn't sound THAT great) and a built in attenuator which is quite useful too. I think these are available on nearly every one of koch's amps. SOUNDS The sound is different because of the El34s of course. The cleans are cleaner and the distortion is warmer and rounded than the studiotone. Of course there's less break up too when you crank the clean cause of the El34s. But aside from that I can't really say that the tones are TOO different, they definitely have the same vibe and the same, let's say, DNA. If you get a chance to play both of them side by side of course you will notice the differences but you will definitely feel the same vibe from both amps. It just depends on your needs in terms of features and how much clean headroom you want that would depend on which amp to go for. OVERALL OPINION Another amazing amp from Koch. Though it has the same soul, it's definitely improved upon with more headroom and separate EQ channels for both clean and dirty channels. All the same as the studiotone with the great tones, the power soak, and the recording out with cab emulation. A very very very worthy amp!!!

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. UTILIZATION 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. SOUNDS 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. OVERALL OPINION 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

Koch has offered the world a great preamp floor unit to go direct into a recording session or even into the house PA system with its built in speaker simulator. This gigantic floor pedal is the answer to someone who needs carry on amp and can go direct into a live show without any cabinets or someone how ever needs to be quite and play silently using the built in headphone jacks. This would also be perfect for someone plugging into their own power amp and using it into their rack system. You can even hook your favorite effects up to it since it has a built in effects loop on the back of the unit. This thing is very well design and uses all the modern world technology to its advantage. UTILIZATION Specifications Koch Pedaltone * All-Tube - 4x 12AX7 tubes * Independent channels - Clean & Overdrive with separate Gain, Volume and Tone controls. *Clean channel w/footswitchable Enhance function *Distortion channel w/ footswitchable High-Gain Boost function *Footswitchable Solo/Rhythm function *Adjustable Footswitchable 0.5 Watt all-tube single-ended power amplifier with Drive and Volume controls *Effects Loop - fully buffered Bypass function Ouputs: To Power Amp (0dBm) To FX Return (-10dBm) To Amp Input (-20dBm, filtered} To Recording (-10 dBm, with speaker simulation) To Headphones (0dBm, with speaker simulation) 12 VAC power supply input - mains adopter is included Dimensions - 31w x 23.5d x 8.5h cm / 12 1/5"w x 9 ½"d 3 1/3"h Weight 3 kg / 6lbs SOUNDS This thing doesn't sound all that great compared to their other amp. This preamp is design to have an array of functionality and use. It does have a broad arrange of possible operations but this tone of it isn't that promising. I really enjoy their powertone amps and their studiotone, but this preamp falls short or anything worth owning. Use this with any guitar you like. I find that the tone is a little buzzy and thin to my ears. So a guitar with a humbucker pickup installed would be optimum. It is nice to have this kind of idea but if it doesn't sound good then it isn't worth it. OVERALL OPINION I am not sure what these pedals come in at the new price. They have been discontinued in some stores and I am not sure the reason behind that. They are very hard to find and many places don't carry them. I have not even seen them on the classifieds or even ebay. There are alternative like Hughes and Kettner makes a similar pedal and of course the V-Twin from Mesa Boogie is always a great option.

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 their high gain ultra goodness amp. This amp is full of character and tonal pleasure. This is a fantastic amp and I don't mind saying one of the best tonal amps that I have ever heard. The Dutch did it right on this amp. This is three channels one for the clean, one for the gain, and the third for the ultra-gain. Each channel has a great tone and not separation that makes them pleasing to the ear. This amp is the same amp as the head version but now in a combo version. You get you 12 inch speakers and nice cabinet to go along with it. This has all the same same features and the rest but just in a nice size combo version. UTILIZATION * 3-Channels: Clean, High-Gain and Ultra-Gain * 4x 12AX7 and 4x EL34 * 3-way Speaker Damping switch * Serial and Parallel FX-loop * Voicing switches on all channels * Solo / Rhythm facility with two independent Master volumes * Accutronics spring reverb * Recording output * 5-way footswitch included * 2x12" Speakers SOUNDS The clean channel is a very good British style clean that is sparkly but nothing like a Fender clean. The clean can chime but not the American style, but a darker clean. The gain channel is enough gain for most players out there. This channel has 4 gain stages and is a beast of a channel for rhythm and lead tones. The ultra gain is just enormous is tone and more gain that a gold vault. This has 5 stages of gain and is a killer channel. There is more gain than humanly possible and more gain than is really needed, but it is always cool to brag about more than enough gain. It is one killer channel and one of the best and most versatile amps that I have ever come across. You still have the ability to hook this cab into another speaker cabinet and bypass the speakers that are in the cab. You also have the recording output to go directly into a house PA or a recording session. OVERALL OPINION This amp also has a voicing switch for all of the channels. I am very surprised that this amp is not more popular than it is because it is a remarkable amp. It also has two separate master volumes for soloing. Add reverb and a recording output and you have one of the most versatile amps on the market. At new these amps come in right at around $2100. That is a great price for the amp combo and the ability to create virtually any tone in the universe.

This amp is the amp as the combo but just in a head version. You get the same great tone and features and a little bit of a cut on the price for a new one. These ar fantastic amp and are extremely versatile. 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. UTILIZATION Specifications Koch Multitone Tube Amplifier * 3-Channels: Clean, Drive and Gain * four 12AX7 preamp tubes * 2 El34's * Speaker Damping switch * Penthode / Triode switch * gold plated jacks * special design 10-wiper pots for long life * ceramic tube sockets w/spring retainers * hand soldered tube sockets * Serial and Parallel FX-loop * Solo / Rhythm facility * Accutronics spring reverb * two Koch VG12-90 speakers (Combo) * Recording output * 5-way footswitch included * 11-layer birch ply cabinet construction * vibration-free MDF baffle boards * proprietary transformers w/Hi Q core SOUNDS I prefer the head version because I would rather play this amp with a 4x12 cabinet. This amp sound better when is gets opened up with 4 speakers and feels better too. This amp gets a little more headroom in the tone than the 50 watts. Also the 50 will feel a little more spongy in the low end because of the lower wattage. 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. OVERALL OPINION At new these amps come in at around $2700, at least that is the lowest I have found which is lower than I could find the 50 watt version. 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 used Bogner for that price and be able to service it a lot easier if anything should ever happen to it.

This amp is the same amp as the 50 watt version but just doubled the power. In this amp you get 100 watts of power. You have all the same tone and features as the 50 but just a little more headroom. The tone will slightly be different because you double the power so you will get some extra headroom in the tone. 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.

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 a 1x12 cab and also a 2x12 cabinet. The 2x12 will sound more open and airy where the 1x12 will have a boxy sound. Each are phenomenal amplifiers and features the same specs and tone but just a slight difference between those two. The head is just that, a head. This amp you will need to have a separate cabinet to plug into. 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.

The 1x12 amp will have a boxier sound but still a very good tone. Each amp is within just a few hundred dollars from one another. And each have a great distortion tone and clean tones. 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.

OVERALL OPINION These amp range from $3300- $2700 depending on what amp it is. That is a hefty price for amps like these. Pretty expensive series of amps and that price is a bit high in my opinion. I would recommend a Bogner or an Egnator to have versatility like this at a much lower price. Well the Bogner would have to be used but a better amp in my opinion.
