A revival of one of the company's legendary amps, the Ampeg V-4B Bass Head employs an all-tube power and preamp, three-band EQ, and selectable mid-tone rocker switch to capture the gritty power of the original. At 100 watts, the V-4B is armed with more than enough muscle to push the 12AX7 preamp and 6L6GC power amp's grinding attack to the back of large venues. Sculpting your assault with the three-position mid tone control makes sharpening, fattening, your expanding presence as easy as dominating the low-end during a show or in practice.
