Hand-built by Bill Finnegan in relatively limited numbers, the original Klon Centaur* guitar overdrive pedal found favour with a number of notable guitarists attracted to its 'transparent' tone — an ability to add gain to the signal without significantly altering the tone of the guitar, in other words, which has been modeled in Clon Minotaur Transparent Overdrive, offered for free by Nembrini Audio as an effect plug-in (and also available for free in an iOS-friendly form on the App Store).
Nembrini Audio says:
Duly depending on the settings of its Gain, Treble, and Output control knobs closely following in the footsteps of the highly collectable hardware from which it takes its inspiration, Clon Minotaur Transparent Overdrive often acts as a clean boost by adding volume and minimal coloring to the sound, which, in turn, can be used to drive the input valve stage of the virtual amplifier to produce the distorted characteristics of an overdriven guitar amp.
