Ampeg

collapse expand iconDescription

The Ampeg V-4B 100W All-Tube Bass Head delivers massive tube tone in a portable design. Perfect for bass players seeking vintage sound and modern power, this head provides a full 100 watts to drive any Ampeg cabinet. With its thoughtful selection of features, the V-4B offers flexible, fully-cranked tone for any gig or studio situation.

All-Tube Design Delivers Legendary Ampeg Sound

Featuring four preamp tubes and two power tubes, the V-4B head generates a fat, warm tube tone that has defined the Ampeg sound for decades. Its carefully tuned preamp and tone stack provide a wide range of sounds, from articulate punch to full-bodied grind. For players seeking a more modern tone, the V-4B also includes a 3-band EQ with flexible midrange control and a bright switch to cut through the mix.

Flexible Output Section Suits Any Setup

With its multiple speaker outputs and DI, the V-4B works for any live or recording setup. Connect to Ampeg SVT or Classic cabinets for a traditional Ampeg stack or use the 8Ω to 2Ω outputs to power other brands. The balanced XLR DI sends your tube tone direct to FOH or recording interfaces. A ground lift switch eliminates unwanted hum and an effects loop facilitates outboard gear.

Portable, Rugged Design

Despite its all-tube design, the V-4B is easy to transport from rehearsal to the stage. Ampeg's unique chassis suspension system reduces vibrations that can damage tubes and components. Premium components like sealed pots, military-grade switches and rugged construction provide years of trouble-free performance under demanding conditions.

On May 1st, 2009, the Mackie, TAPCO, Crate, Blackheart and Ampeg websites will be updated with the addition of warranty URLs (e.g. www.mackie.com/warranty) expressing new A Stock warranty terms. These warranty URLs will go live on May 1st, 2009. Formerly, warranty periods for these LOUD brands appeared in a variety of locations – in product manuals (for Mackie and TAPCO) and on warranty cards and hang tags (for Crate, Blackheart and Ampeg). In order to streamline and clarify this process, Mackie, TAPCO, Crate, Blackheart and Ampeg warranty periods and terms will be communicated in full on the warranty pages. Any LOUD products purchased prior to May 1st will bear with them the manufacturer’s warranty as predates the new policy. Moving through this transition, in order for customers to obtain warranty service, both the sales receipt and a physical copy of the (older) warranty statement will be required by our Service and Support departments in order to issue Service Requests, etc. If the product was purchased on or after May 1st, 2009, but a physical copy of the older warranty terms is not presented, the new warranty terms and periods will apply. Meanwhile, the products that bear with them the new warranty periods (as reflected in the box contents of each product) are being tracked by serial #, and contain new warranty content referring customers to the appropriate brand website.
