TC Electronic Dual Wreck Preamp Preamp/Rack Amplifier

Twin-Channel Rectifier-Style Preamp Pedal for Heavy Tones

The TC Electronic Dual Wreck Preamp brings the unmistakable voice of one of the most iconic high-gain tube amplifiers ever built into a single Ampworx-format pedal. Capturing the authentic feel and emotional response of the original amp was just as important as nailing the frequency curve. This pedal is the right choice for guitarists who want authentic rectifier-style aggression without hauling a full tube head to every gig.

Ampworx Modeling with Celestion Cabinet Authenticity

Rather than offering dozens of amp models, TC Electronic focused on replicating a single legendary amplifier with absolute precision. The unit ships pre-loaded with the official Celestion impulse response of Vintage 30 speakers in a closed-back 4x12 cabinet, giving the DI and headphone outputs a genuine mic'd-cabinet response. Custom IRs can also be loaded through the USB port.

Two Independent Channels with Full Tone-Shaping

The dual-channel design lets players store two different high-gain voicings and switch between them with a dedicated footswitch, eliminating the need for a separate clean preamp.

• Number of Channels: 2 — independent Gain, Tight, Level, Bass, Mid, and Treble per channel
• Tight Control: 0–full range — adjusts low-end response from loose and fat to immediate and focused
• Global Presence: rear-panel knob — fine-tunes overall high-end bite to match any amp pairing

Pre/Post Boost and Flexible Output Routing

A dedicated Boost footswitch adds either a clean volume lift or a saturated drive, depending on where it sits in the signal chain. All three outputs can run simultaneously.

• Boost Modes: Pre / Post switch — Post is a transparent volume boost; Pre drives the amp modeler like a vintage tube screamer
• Outputs: 6.3 mm TS Line OUT, 6.3 mm TS DI with Cab Sim, 3.5 mm TRS Headphone with Cab Sim
• Inputs: 6.3 mm TS instrument input, USB port for firmware updates and IR loading

Compact Stompbox Hardware for Any Pedalboard

Top-mounted jacks make this unit pedalboard-friendly, while the metal chassis and smooth-feeling knobs are built for daily gigging use.

• Dimensions: 113 × 51 × 136 mm — fits standard pedalboard layouts
• Weight: 0.53 kg — light enough for fly rigs
• Power: 9 V DC, 300 mA, centre-negative barrel plug (5.5 × 2.1 mm)

For Metal, Grunge, and High-Gain Players Seeking Amp-Like Feel

Built for guitarists who live in the world of palm-muted riffs, sustained leads, and tight low-end response — from bedroom producers tracking through an audio interface to touring players feeding a power amp on stage. The unit excels at late-90s new metal tones when boosted, classic post-grunge crunch unboosted, and pop-punk rhythm work. Players with a clean amp platform will find this pedal slots in as a complete rectifier-style voice, while silent-practice users can plug straight into headphones.

TC Electronic's Ampworx Approach

The Ampworx series pairs component-based amp modeling with curated Celestion cabinet impulse responses. The engineering team focused on capturing one iconic amplifier per pedal with absolute precision, then added practical features like the Pre/Post Boost, global Presence, and simultaneous DI/headphone outputs.
