TC Electronic V550 Preamp Pré-amplificador/amplificador em rack

TC Electronic V550 Preamp — 5150 Mk1 Tone in a Stompbox

The TC Electronic V550 Preamp pedal delivers the iconic high-gain voice of the 1992 EVH MK1 5150 tube amp on any pedalboard through TC's Ampworx modeling engine. Two channels — Green for crunchy rhythms and Red for saturated leads — give players the full tonal range that made the original a metal and hard-rock staple. This model is the right choice for guitarists who want authentic 5150-style gain without hauling a tube head to the gig.

What Sets This Preamp Apart in the Ampworx Lineup

Unlike generic amp-in-a-box pedals, the V550 ships with an official Celestion 4x12 G12M Heritage impulse response loaded into the DI and headphone outputs — no third-party IR loader needed. The rear-panel Pre/Post boost switch is a feature the original 5150 never had: Pre mode pushes the model harder for vintage-style saturation, while Post mode delivers a clean 5 dB volume lift for soloing. A dual-channel memory function recalls each channel's knob positions automatically.

Two-Channel Architecture with Independent Tone Shaping

The dual-channel design is what makes the V550 feel like a real amp rather than a single-voice pedal. Each channel stores its own settings independently.

• Channels: 2 (Green / Red) — independent Gain, Level, Resonance, Low, Mid, and High per channel
• EQ Section: 3-band Low / Mid / High — interactive tone stack that responds to playing dynamics
• The unit also features a global Presence control, which is a rear-panel knob that adds brilliance and warmth across both channels simultaneously.

Boost Circuit and Output Routing

A footswitchable boost and three independent outputs make the V550 equally useful on stage, in the studio, or for late-night practice. The Pre/Post switch decides whether the boost hits the amp model first or sits after it in the signal chain.

• Boost Level: 5 dB — fixed gain lift, footswitchable for instant lead switching
• Boost Placement: Pre / Post switch — Pre drives the model harder; Post lifts volume transparently
• Three simultaneous outputs (1/4" TS line, 1/4" TS DI, 3.5 mm TRS headphone) provide the Celestion 4x12 G12M Heritage IR on DI and headphone paths.

Pedalboard-Ready Hardware and Power

At 0.49 kg in a compact 13.7 × 11.4 × 5.1 cm enclosure, the V550 fits standard pedalboard layouts without dominating real estate.

• Bypass: Buffered Bypass — preserves signal integrity across long cable runs
• USB: Mini-USB — firmware updates only, no audio streaming
• Power requirements are 9V DC at 300 mA, which matches standard pedalboard power supplies sold separately.

Built for High-Gain Players Who Need Amp-Free Rigs

This instrument is the right choice for metal, hard rock, and modern rock guitarists who need the 5150 Mk1's aggressive voice in a pedalboard-friendly format. Worship players running silent stages, home recordists feeding an audio interface, and touring musicians flying without a full backline will all find the DI and headphone outputs especially practical.

Ampworx Series — Component-Based Amp Modeling

TC Electronic launched the Ampworx series to bring component-level amp modeling to the pedal format, modeling each stage of the original circuit rather than snapshot profiling. The V550 targets the 1992 EVH MK1 5150 — the amp Eddie Van Halen used through his later career and the head that became a metal-standard tone after Peavey's 6505 variant.
