Ampeg SVT-3PRO Bass Amplifier Head

The Ampeg SVT-3PRO delivers classic SVT-inspired bass tone, deep tonal flexibility, and professional touring performance in a compact rackmount hybrid amplifier head.

• 450-watt hybrid bass amplifier head with tube preamp and solid-state power section
• 3 x 12AX7 preamp tubes plus dedicated driver tubes for classic Ampeg warmth and dynamics
• 9-band graphic EQ and 5-position midrange selector for precise tone shaping
• Tube Drive control adds everything from clean articulation to warm tube saturation
• Professional rackmount touring design with extensive stage and studio connectivity

The SVT-3PRO has earned its reputation as one of the most respected professional bass amplifier heads in modern Ampeg history. Combining the warmth and responsiveness of a tube preamp with the reliability and power of a solid-state output section, it delivers unmistakable SVT-inspired character in a highly flexible rackmount format.

Its hybrid architecture features three 12AX7 preamp tubes alongside dedicated driver tubes that help deliver the rich harmonic response, punch, and low-end authority bass players expect from Ampeg. The Tube Drive control allows players to move from clean articulate tones to warmer compressed textures and aggressive overdriven character while maintaining excellent responsiveness and clarity.

The SVT-3PRO is built for players who demand serious tone shaping capability. A highly flexible 3-band EQ is paired with a 5-position midrange selector and switchable 9-band graphic EQ, allowing bassists to precisely tailor their sound for studio recording, live performance, or complex touring rigs.

Professional features like transformer-balanced XLR direct output, effects loop routing, dedicated tuner output, multiple speaker connections, and rackmount construction make the SVT-3PRO equally comfortable on major stages, touring systems, and professional studio setups.
