SWR Amplification WORKINGPRO-400
Bass Amplifier Head, 400W @ 4 ohms

WORKINGPRO-400

Loaded with the same exact feature set as the trendsetting WorkingPro 700, the WorkingPro 400’s 400 watts go a lot further thanks to SWR's exclusive Bass Intensifier circuit. It takes frequencies from 20 Hz up to a selectable frequency between 80 Hz and 200 Hz, then boosts and compresses them at the same time for optimum impact on the overall low end. The result is a thicker, fatter, faster bass response – perfect for thickening up that bridge-pickup "Jaco" sound, or just dropping a sub bomb on the audience whenever you feel the need.
