Koch Pedaltone II overview.
When Dolf Koch decided to design a tube preamp for guitar, he felt it should combine as many high quality features as possible. The result of his effort is the Pedaltone. Heavy duty components, housed in a stainless steel shell, combine two individually controlled channels with a host of options that leave the user with no less than 16 separate sounds at his discression!
Channel 1 Clean, Channel 1 Enhanced, Channel 2 Distortion and Channel 2 Distortion Boost provide the first four sounds.The first three 12AX7 preamp tubes send these classic Koch tones to virtually any input imaginable: from your favorite amp to any type of recording/PA console. The fourth 12AX7 tube acts as a 0.5 watt Power Amp, with its own Gain & Volume controls, adding depth and attitude. In the original version this feature was called “Power Amp” but in version II we named it “OTS” (Output Tube Saturation).
It has also been redesigned for a fatter tone, and relocated Post effects loop instead of pre effects loop. Combining this OTS feature to any of the first four sounds now gives the user the option of eight individual and unique settings. The final feature on the Pedaltone, the famous Koch Solo/Rhythm control, has been replaced with two separate foot-switchable Master Volumes: Rhythm and Solo volume. Engaging this feature allows the user two (foot-switchable) volume levels per setting (a user controllable ‘Rhythm’, and a user controllable ‘Solo’ volume) doubling the number of settings available to 16.
Last but not least, the FX Loop allows the addition of your favorite effects, while the Headphone jack allows the Pedaltone to be used anywhere… anytime.
OTS function explained
OTS stands for Output Tube Saturation. We have built in an All-tube, single-ended, 0,5W power amp with drive and volume controls. This will give you the effect of an all-tube amp fully driven. What you'll hear is a great saturated sound from power tubes played to their max capacity. This function can be added on all channels, and thus gives you more sounds at your disposal. The OTS is placed between the pre-amp and power-amp section. This function is a unique “Koch” feature!
