Half the weight of an SVT head, this reissue of the legendary Ampeg V-4B bass head cranks 100 watts of all-tube power with all the rich tone of the original.

Celebrate Four Decades of All-Tube Bass Tone!
A reissue of a classic model, the Ampeg V-4B is a tried-and-true 100-watt all-tube bass head. With a design dating back to 1971, the V-4B has proved to be a reliable warhorse with a great sound ever since. This most recent release adds a few helpful modern features, while staying true to the legendary tone of the original.

8 Tubes in All
If you open up the Ampeg V-4B, you'll find 2 x 12AX7s in the preamp section, generating the rich tonal core of your bass sound. After this, the 12AX7 and 12AU7 Driver Tubes crank up your gain to drive the speakers in your cabs. The Power Amp section is comprised of 4 x 6L6GCs.

No-Nonsense Controls
The front control panel gives you a Normal and a -15dB input jack for the single channel amp. Here you'll also find Gain, Bass, Midrange, and Treble EQ knobs. A Standby switch at far right lets you cut the signal momentarily when needed.

Modern-Day I/O Setup
On the rear panel you'll find Preamp Out and Power Amp In jacks for running an FX loop. There is also a 1/4-inch Slave output for pushing the front end on another amp, or running direct into a PA or mixer. A single balanced XLR output is here as well. A Ground Lift switch helps you cut buzz when it arises.

Versatile In Use
Running to external cabinets, you can run to a single speaker at 8 ohms, a stereo pair at 4 ohms, and 4 speakers at 2 ohms nominal impedance.
