SWR SM-400 Bass Amplifier Head

Description

The SWR SM-400 is a legendary bass amp head known for its clean headroom, punchy response, and studio-quality tone shaping. A staple in the 80s and 90s touring scene, this amp delivers that signature SWR clarity—tight, defined lows with crisp highs and articulate mids that let every note speak clearly.

Rated at 400 watts in bridged mono (or 200 watts per side in stereo), the SM-400 offers flexible power configurations for a variety of cabinet setups. Its onboard Aural Enhancer circuit helps sculpt a modern, hi-fi bass tone, while the comprehensive EQ section gives you deep control over your sound. Whether you're playing funk, rock, gospel, or fusion, this head provides the clean power and tonal versatility needed for live performance and studio applications.
