As in the original, the inspiring round, fat WalkAbout Tone is joined by comprehensive rotary shelving Tone controls and a semi-parametric EQ, giving you total shaping authority in the preamp. The new WD800 also features the Subway D800 Plus’s highly effective HIGH PASS FILTER and a new POWER AMP DAMPING control, which allow tuning of the sub-low frequencies and power response options respectively. The POWER DAMPING choices enable you to tailor the tracking and feel of the power amp. The LOW setting produces a looser, more relaxed and blooming character reminiscent of Tube power. HIGH tightens the low end, adding punch and accuracy in tracking, while MEDIUM provides a blend of these opposite ends of the power response spectrum.
