The Oberon is a treble booster that utilizes a NOS PNP germanium transistor, designed for a focused frequency enhancement similar to classic Rangemaster units. This pedal features a straightforward interface with a single Boost knob and a three-position toggle switch to select frequency ranges.
The High setting emphasizes treble while reducing mids and lows, the Mid setting cuts most low frequencies, and the Low setting provides a full-range boost. Users can adjust the overall intensity using their guitar's volume knob or the internal gain trim pot, making it easy to achieve the desired sound without constant tweaking.
