Used Ampeg SVT-4PRO Rackmount Bass Amplifier Head

The Ampeg SVT-4PRO is a beast of a rackmount bass amp head, built to deliver serious power and flexible tone-shaping for players who need it all. With a tube-driven preamp and a solid-state power section, this amp pushes up to 1600 watts in bridged mono mode—plenty of muscle to drive any stage rig. It’s got an extensive EQ section with a 9-band graphic EQ, ultra-mid control, and deep/bright switches, giving you everything you need to dial in your perfect sound.

This amp is a favorite among touring bassists and studio pros for good reason. It brings that classic Ampeg punch and warmth, but adds a level of control and clarity that modern players love. The dual-mono or bridged output options give you the flexibility to match it with multiple cabs or run a massive mono rig. Whether you play funk, metal, jazz, or anything in between, the SVT-4PRO gives you tone for days.
