The SWR SM-900 is widely regarded as SWR's flagship bass amplifier — a tube preamp / solid-state power amp hybrid delivering up to 900W bridged mono (4Ω) or 400W per side in stereo. Features dual independent, footswitchable 3-band semi-parametric EQs, Aural Enhancer, adjustable limiter, built-in active crossover, stereo/mono effects loop, tuner send, and balanced XLR output with pad and ground lift.
This unit has been case-kept in our warehouse for years and is in excellent condition — minimal wear, all functions fully tested and confirmed working with no crackle or signal issues across every knob, switch, and EQ section. Rack-mountable (2U), built in the USA.
Sold by Square Wave Productions, a professional live production and audio company — this amp comes from our own touring/studio inventory, not a reseller lot.
