The 400 PRO is a truly professional-grade combo. For bassists looking for a versatile high-powered, hi-fi amplifier that’s incredible-sounding, easy to use and portable, the 400 PRO delivers!

The 400 PRO pushes 350 watts at 4 ohms (500 watts at 2 ohms) out of two 10” Fender Special Design Eminence cast-frame speakers. Other features include a five-band EQ (including a three-band semi-parametric EQ with gain control and on-off switch), adjustable compressor, room balance control (compensates for extreme acoustics), "enhance" switch that emphasizes highs and lows, and a balanced XLR line out with a pre/post EQ switch.
