Warwick Amps MS 800 - Multi Stage Bass Amp Head 800 Watt

The Warwick MS 800 Multi Stage Bass Amp Head is a compact, ultra-versatile powerhouse designed to give your bass a precise, punchy and modern voice in any situation. Delivering up to 800 watts of solid-state Class D power, dual channels with independent drive, onboard compression and full connectivity including Bluetooth and USB, it is built for players who need studio-level control and live-ready muscle in one portable head.

From clean, hi-fi tones to snarling overdrive, the MS 800 lets you shape every detail of your sound with a flexible 4-band EQ and selectable mid frequencies. With an integrated tuner, cab emulator, FX loop, DI out and bi-amp line out, it slots effortlessly into any rig, whether you are rehearsing with headphones, tracking in the studio or pushing a full stack on stage.

Powerful, Portable Class D Performance

At the heart of the MS 800 is an efficient Class D power section delivering 800 watts at 4 ohms or 480 watts at 8 ohms. This gives you the headroom to stay tight and articulate at gigging volumes while keeping the unit compact and lightweight for easy transport. The solid-state design keeps your tone consistent night after night, with fast, controlled low end that cuts through the mix.

Dual Channel Design with Independent Drive

The dual channel layout offers two fully controllable stages, each with its own DRIVE control and dedicated front panel switch. You can set one channel for pristine cleans and the other for gritty, harmonically rich overdrive, then switch between them instantly from the front panel or via an optional footswitch. Stacked controls for Drive, Gain, EQ and Volume keep the front panel compact while still giving you precise control of both channels.

Flexible Tone Shaping and Compression

A 4-band EQ with selectable Lo Mid and Hi Mid frequencies lets you dial in anything from vintage warmth to modern, scooped or mid-forward tones. The onboard compressor features stacked Amount and Level controls plus a dedicated switch, allowing you to tame peaks, add sustain or tighten your attack without extra pedals. LED indicators for clipping, channel status and compression keep you fully informed of what the amp is doing at a glance.

Modern Connectivity for Stage, Studio and Practice

The MS 800 is equipped with Bluetooth and USB connectivity, an Aux In, headphone output and an integrated tuner, making it a complete hub for practice and recording. On the rear panel you will find a balanced XLR DI with Pre/Post switch and ground lift, a cab emulator with three selectable modes, an FX loop with send and return level controls, and a line out with FullRange/Bi-Amp switch. Whether you are sending a cab-sim signal to front of house, running bi-amp setups or tracking via USB, the MS 800 is ready to slot into any workflow.
