Seymour Duncan Forza Overdrive Pedal Gain Control Range: 11dB to 37dB Bass: 90 Hz +/- 11dB Mid: 750 Hz +/- 11dB Treble: 2.1 kHz +/- 12dB Bypass (Footswitch): Engages the overdrive effect Input impedance: 470k Ohms While many overdrives emphasize particular frequencies, the Forza gives you a more even spread across the frequency range The voicing is very open, and it sounds just as good through a clean channel or hitting an already-overdriven amp In addition to up to 37dB of gain theres a three-band EQ for controlling the lows, mids and high end, and the Level control has plenty of range to allow use as a clean boost too The Forza uses a glass diode, back-to-back stack overdrive circuit
