The ClinchFX Burnish Boost is effectively a miniature class A amplifier with an output transformer. It can generate approximately 18dB of clean boost before clipping, depending on input levels.
If our EP-PRE is a “Tone Polisher”, our Burnish Boost is a burnishing tool, leaving its impression but keeping the essence of your tone.  The impression it leaves is a gentle mid presence boost, and a slightly rough edge that endows it with an aura of character. The design is original, and has no common circuitry with our EP-PRE, however we designed it to exhibit a similar Phase Response to the EP-PRE, giving it a rich, full-bodied tone.
The Burnish is a relatively clean boost, but, if you drive it hard enough it will gradually be forced into soft, progressive clipping, in a similar way to a class A Tube amp.  We adapted one or two design features from classic tube circuitry, ensuring that there is none of the harsh clipping that is usually associated with solid state amps.
