Critic Reviews

Ampeg V-4B review | Guitar World

guitarworld.com

Ampeg’s V-4B is a compact powerhouse that captures the brand's iconic all-tube sound in a more manageable package. With its classic aesthetics and solid 100-watt output, it stands as a worthy alternative to the mighty SVT for those who don't need excessive clean headroom. The V-4B shines with its dynamic range, delivering everything from creamy overdrive to powerful tubbiness. However, its limited clean headroom at high volumes might not suit every bassist's needs. Ideal for players appreciating vintage charm and tonal versatility without the heft of the SVT.
