Citadel Plutonium Overdrive - Total Bass Annihilator

Citadel Plutonium Overdrive – Analog bass overdrive with flexible tone control

Citadel Plutonium Overdrive is an analog distortion pedal designed specifically for electric bass. Built around an op-amp circuit and featuring the unique Crush control, it offers everything from tight modern drive to rich, organic fuzz. Suitable for both studio work and live performance where clarity, dynamics and low-end definition are key.

Overview and features

Plutonium Overdrive is tuned to preserve clarity and punch across the low-frequency range. The Blend knob allows seamless mixing of clean and distorted tones, while Drive adjusts the gain level. Bass and Treble controls provide broad EQ shaping for tonal balance across different amplifiers and speaker systems.

The integrated True Bypass circuit with “Initial State Switch” lets you decide whether the pedal powers up in engaged or bypass mode – ideal for complex live pedalboards.

Construction and components

The pedal features a durable metal enclosure that protects the op-amp circuitry and ensures long-term reliability. The control layout is intuitive, providing easy access on stage or in studio setups.

Connections and power

Citadel Plutonium Overdrive runs on 9 V DC (center negative) and draws 50 mA. It features standard 6.3 mm input and output jacks, 1 MΩ input impedance, and 1 kΩ output impedance, ensuring compatibility with most bass rigs, DI boxes, and recording interfaces.

Controls and operation

• LEVEL – adjusts output volume.
• CRUSH – shapes the low-end response before distortion, shifting from tight overdrive to saturated fuzz.
• BLEND – mixes clean and distorted signals.
• DRIVE – sets distortion intensity.
• BASS – ±18 dB shelving EQ.
• TREBLE – ±15 dB shelving EQ.
• TRUE BYPASS / INITIAL STATE SWITCH – selects whether the pedal powers up engaged or bypassed.
