Crushing volume, 2 killer effects, and pure SWR tone. The SWR 750x is the first upgrade to the highest-powered mono professional bass amplifier, the Bass 750. In addition to new chassis graphics — featuring the SWR logo badge in classic chrome — the 750x has inherited 2 popular effects circuits from the SWR Mo' Bass: SubWave (which produces a clean, pure and accurate octave effect) and Overdrive (which affects the pre-amp's 12AX7 tube to create overdrive that can be as subtle as a classic "flip top" or as nasty as a half stack).
