Koch The Greg Koch Signature Combo
Amazing signature combo amplifier from Greg Koch in Cool Blue Tolex, built by Koch!
If there is one guitarist who has experience with guitar sound, it is American Blues and Rock legend Greg Koch. Just consider the hundreds, if not thousands, of hours of guitar demos on YouTube, not to mention his decades of session and live experience. A more than seasoned player, it is therefore not surprising that his signature amplifier combo is an absolute hit.
The Greg is powered by six 12AX7 tubes in the front stage and two EL34 power tubes. Thanks to this combination, the amplifier has a crystal clear midrange that remains intact no matter what settings you use. And there are quite a few settings, because the Greg uses 3 channels: Clean, Overdrive and Overdrive+Boost. The clean channel is also really clean thanks to the 50 Watt power of the amplifier, and is capable of a lot thanks to the spring reverb and smooth built-in tremolo. The 2 overdrive channels are extremely flexible thanks to the optional OTS (output Tube Saturation) function, which gives the whole thing a big kick in the midrange. Do you want bluesy, low gain? No problem. Are you looking for fusion-like, singing sustain? Hit the Gain boost and OTS and Greg is done!
In terms of sound, the Greg has a vintage slant, but in terms of features it is completely contemporary. Thanks to the built-in effects loop and recording output, the amplifier can be used in any possible setting, whether in the studio or live. In addition, the order of the Reverb and Tremolo is adjustable, so that you have maximum control over the sound.
