Ampeg Reintroduces V-4B All-Tube Bass Amplifier

Ampeg has reintroduce the V-4B, a 100-watt all-tube bass amp. Based on the company’s classic amp from the ’70s, the new head is described as offering the tone of an SVT while weighing half as much.

Ampeg V-4B All-Tube Bass Amplifier Head

The new V-4B’s preamp includes a pair of 12AX7 tubes while the driver has a 12AX7 and one 12AU7, and its power amp contains four JJ 6L6GC tubes. Building upon an innovation from the original V-4B, the new head has a special floating suspension chassis that’s rubber mounted to isolate vibrations to the amp’s tubes. The circuit has a 3-band EQ that includes a 3-position mid-range control to toggle the midrange knob to control 220Hz, 800 Hz, or 3000Hz. Ultra-Hi and Ultra-Lo boosts offer further tonal shaping.

The back of the V-4B offers a Preamp Out, a Power Amp In, a Slave Out, and a balanced XLR output. The speaker outputs has separate 8, 4, and 2-ohm outputs for different cabinet combinations.

The Ampeg V-4B will be shipping later this month with a street price of $1,299. For more info, check out the Ampeg website.
