Ampeg’s V-4B reissue emulates the 1971 version of the original and produces 100 output using four 6L6GC power tubes and two 12AX7 preamp tubes. It has a master Volume along with controls for Bass, Mid, Treble, Gain, and rocker switches to boost/cut ultra-low and ultra-high frequencies, as well as a midrange boost that can highlight 220, 800, or 3,000 Hz frequencies. Modern appointments include an integrated DI with ground lift, -15dB input for active basses, and a range of speaker outputs at different impedances. For more, visit www.ampeg.com.
