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.\u003c\/p\u003e\n\u003cp\u003e 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!\u003c\/p\u003e\n\u003cp\u003e \u003cspan\u003eIn 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cspan\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/1U3l1dXKER4\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003eModel Name: The Greg Koch Signature Combo\u003cbr\u003e Series: Signature\u003cbr\u003e Amplifier Type: Tube\u003cbr\u003e Inputs: 1\u003cbr\u003e Channels: Three foot-switchable channels: Clean, Overdrive and Overdrive Boost\u003cbr\u003e Wattage: 50 Watts\u003cbr\u003e Speaker: 2x 10” Jensen Jet C10-40 speakers\u003cbr\u003e Controls: Separate Drive, Volume and passive Bass-Mid-Treble tone controls for both channels, Foot-switchable OTS (Output Tube Saturation) with Drive and Volume controls, Foot-switchable tube Tremolo with 'Harmonic' and 'Normal' mode, and Speed, Depth and Level controls, Foot-switchable Reverb with Dwell, Tone and Volume controls, and a classic long scale model spring reverb tank, Sequence switch to select Reverb\u0026gt;Tremolo or Tremolo\u0026gt;Reverb, Penthode (full power) \/ Triode (half power) switch, Presence control \u0026amp; Master Volume, Buffered Serial or Parallel effects loop with Level control, Recording output with passive speaker emulation filter\u003cbr\u003e Pre Amp Tubes: 6 x 12AX7 pre-amp tubes\u003cbr\u003e Power Tubes: 2 x EL34 power tubes\u003c\/span\u003e\u003c\/p\u003e","brand":"Koch","offers":[{"title":"Default Title","offer_id":42947577905370,"sku":"2-TG50\/C210","price":1799.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2160\/4507\/products\/IMG_3171_57c828fa-87a8-4db8-9501-1003264e6201.jpg?v=1657102658"},{"product_id":"koch-greg-koch-the-little-gristle-1x12-combo","title":"Koch Greg Koch the Little Gristle 1×12 Combo","description":"\u003ch2\u003e The First Batch in Europe, Now Available at Dijkmans!
