The Tube Nightmare is an enhanced take on a classic screaming overdrive circuit, adding three new controls for ultimate tonal flexibility. A Clip knob smoothly blends from aggressive, low‑volume distortion to clean, high‑output drive for dynamic expression. Bass emphasizes low‑frequency punch before the gain stage, while Bright sculpts post‑drive presence from warm to chime‑bright. Drive offers an extended sweep beyond the original design, delivering both subtler breakup and heavier saturation extremes. Tone provides mid‑forward voice shaping, and Level controls the final output intensity to balance your rig. With support for higher voltages up to 18 V, it unlocks extra headroom while staying true to boutique character.
