PRODUCT DESCRIPTION
Improving on greatness. SWR's 350x is the third in a series of upgrades to SWR's top-selling Bass 350 amplifier. In addition to new chassis graphics — featuring the SWR logo badge in classic chrome — the 350x has inherited the SWR Mo Bass' popular SubWave effect, which produces a clean, pure and accurate octave effect. A Subwave Footswitch with a hardwired 1/4 in. cable (for connection purposes) ships with the 350x as an added bonus.
