Like-new Electro-Harmonix Spruce Goose Overdrive pedal along with original box and box docs. Tested works perfectly. Clean velcro on bottom, board ready. The engine of the Spruce Goose is an overdrive circuit renowned for its natural breakup and amp-like response. This circuit is then elevated to new heights by the LIFT switch which selects between 3 levels of input gain. LIFT effectively works as an input boost, goosing the front end of the drive circuit hitting harder and producing a more compressed, saturated tone while still retaining its dynamic feel and transparent tone. GAIN and VOL knobs adjust for exact drive and output levels. EQ of the pedal consists of a TREBLE knob for taming topping and an active BASS knob to cut or boost bass frequencies. BASS is especially helpful for adding girth to single coil guitars or tightening the low end on warmer humbucker guitars.
