Ampeg V-4B Bass Amplifier Head (100 Watts)

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.

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.

Ive had this amp for a few months with the intention of running guitar it easily does it. Clean is loud but not overbearing like most high gain guitar amps. Amp takes pedals like a dream. This amp is super loud wether bass or guitar the tone is there at loud volume however if you intend to record quiter it needs a little dial in here and there but not much at all. Im running it through a 4x12 8 ohm cab with celestion g12t-70s pretty good combo with any celestion but so far i have the tone ive been searching for forever. Anyone looking for a powerfull clean amp and running low tuned guitars (B or lower) should definitely try this amp.
