PEDAL FUNCTIONALITY FEATURES AND CONTROLS:
TONE:Controls the treble response of theeffect. The Centre point (12:00) is flat. When turned to the left, it cuts treble, and when turned to the right, it boosts treble.
DRIVE:Controls the amount of gain in the op-amp feedback diode clipping stage.
VOLUME:Controls the overall output of the effect
CLIPPING:The downward position of the toggle switch is the stock Tube Screamer clipping arrangement, which has one silicon diode in each direction. The upward position of the toggle is two diodes in each direction, a higher clipping threshold with a more open sound. The centre position leaves only the LEDs for a more dynamic and transparent tone.
BASS:The bass switch selects between different EQ settings. Using the default configuration, the centre position is the stock Tube Screamer bass setting. The downward position adds more bass, and the upward position adds even more.
The build incorporates a 12 mm diameter Blue LED ring around the soft touch Taiway foot operated switch, The Foot switch LED is serviceable by simply unplugging the 2.54 mm JST PCB header Connector.
The pedal consists of 2, PCB’S, all of which can be removed and made serviceable by removing the three JST miniature plugs
The pedal foot switch has a conical dress nut that cab be removed by simply unscrewing, removing the dress nut allows more of the 12 mm Blue LED to be more visually prominent.
DC jack external supply is protected against incorrect polarity, the pedal will just not function until you correct the polarity of the DC 9 Volt 2.1 mm plug (centre pin is negative)
