The Ampeg V-6B was a bass-optimized version positioned between the V-4B and the SVT in Ampeg's 1970s tube amplifier lineup, likely producing approximately 150 watts from six output tubes. It shared the V-series preamp heritage adapted for bass use while offering more output power than the V-4B's 100 watts for players who needed headroom without the full 300-watt SVT. The V-6B is a relatively uncommon Ampeg model and is primarily known through service documentation rather than widespread historical use.
