Ampeg SVT-3PRO Bass Amplifier Head

Ampeg · amplifier

The Ampeg SVT-3PRO is a 450-watt hybrid bass amplifier head combining a tube preamp with a solid-state power amplifier in a 2U rack-mount chassis. The tube preamp section employs 12AX7 and 12AU7 tubes to deliver the harmonic warmth characteristic of the SVT lineage, while the solid-state power stage provides output reliability and efficiency for touring use. A 9-band graphic EQ, Drive control for tube-like grit, and independent gain and master volume controls allow tones from clean and punchy to thick and saturated. Extensive connectivity including effects loop, balanced XLR DI, and bi-amp output makes it versatile as both a live and studio tool, and its rack-mount format suits players who run modular rig configurations.

  • “The trade-off compared to the all-tube SVT-CL is some loss of dynamic warmth in the power amp section, audible mainly when the all-tube version is being pushed hard”

    — from the reviews

  • “The 9-band graphic EQ and Drive control give exceptional tonal control, from clean country thump to heavy tube saturation”
