V-4B Old vs. New Head to Head | Bass Gear Magazine

bassgearmag.com

The Ampeg V-4B Reissue pays homage to its vintage predecessor while bringing modern improvements. Despite lacking an electrical clone of the old V-4B, it shines with practical updates like lighter weight, modern tube selections, and a versatile DI output. The new model's EQ flexibility, with a modern Ultra Lo switch, caters well to rock players seeking that familiar tone. While the vintage V-4B boasts better power and a nostalgic aesthetic, the reissue offers more consistent distortion control and versatility, making it a gig-friendly choice. A nod to the old, but the new V-4B takes the crown for usability and serviceability.

Ampeg V-4B review | Guitar World

guitarworld.com

Ampeg's V-4B reissue is a throwback delight for bassists who crave vintage tube tones without the weight of an SVT. It offers the signature Ampeg sound with creamy overdrive and dynamic performance in a manageable 41-pound package. However, it does have limited clean headroom at higher volumes. Perfect for those who love the warmth and responsiveness of tube amps, the V-4B shines with its righteous grind when pushed hard. While it may not replace the SVT for sheer power, it certainly captures the essence of Ampeg's legendary sound in a more accessible form.
