The 250-X features the same Gain and Level control potentiometer values and tapers as the original OD250, providing the familiar control knob feel and range that users have come to expect. The 250-X includes the new 3-position toggle switch that not only faithfully replicates the original 250 stock “SILICON” mode but also includes two additional modes for additional versatility. The “ASYM” mode provides an entirely different asymmetrical even-harmonic distortion characteristic. The third toggle switch selection is a “LIFT” mode which eliminates diode clipping entirely from the signal path, providing a clean boost at moderate levels, or even a “dirty” boost as you drive the LM741 op-amp into clipping at higher gain settings. - 10th iteration of the 250 Overdrive/Preamp - LM741 vintage- style op-amp - 3 Selectable Voices (Silicon, Lift, Asym) 1. Silicon (Up) enables the classic 250 odd-harmonic-dominant sound of symmetrical anti-parallel silicon clipping diodes. 2. Lift (Middle) eliminates all diode clipping, essentially turning the 250 into a simple boost pedal which can provide clean boost at low gains and dirty boost at higher gains. 3. Asym (Down) enables the unique even-harmonic-rich sound of the asymmetrical clipping circuit topology. • Modern 9V DC Power supply input • 18V Tolerant Circuitry • True Hard-Wire Bypass • The Most Versatile 250 ever
