Selling a heavily upgraded, custom-voiced Randall RD1 Diavlo 1-Watt tube head. If you know these amps, you know they sound massive for high-gain chugging but suffer from a stock factory flaw: the tone knob sweep is notoriously dark, muddy, and useless on the lower half of the dial.

This amplifier has been completely cured of that issue. It has been modified with an external 3-Way Custom Voicing Switch wired directly into the preamp layout, transforming this from a standard low-wattage bedroom chug machine into a universal, multi-textured metal monster.

The 3-Way Custom Voicing Mod:

- Position 1 (Left Toggle): LED Clipping Mode. Engages a unique diode clipping stage that adds a smooth, aggressive crunch and tight dynamic texture that tracks your playing perfectly.

- Position 2 (Center Toggle): Wide-Open Mod Mode. Completely opens up the circuit path. This removes the original choked filter, unlocking a bright, articulate tone sweep across the entire range of the dial. No more mud, no more blankets over your speaker—just pure, aggressive bite even at low dial settings.

- Position 3 (Right Toggle): Original Factory Setting. Re-engages the original factory routing layout if you ever want that warm, deeply compressed, classic dark sweep.

Upgrades & Enhancements:

- Brand New Matched JJ Tubes: Fully serviced with a fresh, premium matched set of JJ tubes for maximum headroom, reliability, and thick harmonic saturation.

- Internal LED Strip Lighting: Outfitted with an internal LED lighting setup that gives the chassis an awesome, aggressive glow through the front mesh grille.

- Custom Cosmetic Restyling: The original vinyl corners had some typical wear and tears, so it has been upgraded with sleek, high-gloss black accent side panels. It looks incredibly sharp, unique, and clean on any desk or speaker cab.

Condition & Functionality:

The amplifier is in excellent, fully functional condition. Pots are clean, inputs are solid, and the custom toggle switch operates flawlessly with zero dead spots. Perfect for a studio recording tool or the ultimate bedroom shred rig.
