SWR Stereo 800 Bass Power Amp

The SWR Stereo 800 is one of those old-school rack power amps that quietly reminds everyone why SWR had such a loyal following. It’s big, unapologetically heavy, and delivers that clean, hi-fi punch that bassists still chase decades later. This thing doesn’t colour your tone — it just takes whatever your preamp gives it and makes it louder, tighter, and very confident about it.

Designed as a true stereo power amp, the Stereo 800 gives you plenty of flexibility for bi-amped rigs, dual cabs, or running separate signal chains without compromise. It’s fast, responsive, and stays composed even when you lean into it hard — the low end stays solid, the highs stay clear, and it never feels like it’s running out of breath halfway through a set.

If you’re into rack rigs, classic SWR tone, or just want a no-nonsense power amp that does the job properly (and weighs about as much as your first car), the Stereo 800 still earns its place. Built for serious stages, serious volume, and bassists who like their gear loud, clean, and slightly intimidating — in a good way.
