The 500-watt RB-210 is the ideal portable gigging amp. Dual custom 10" Eminence speakers coupled with a mutable high-frequency horn reproduce a wide range of bass sounds, while classic Ampeg 3-band EQ, Ultra Hi/Ultra Lo switches, and the new Super Grit Technology overdrive circuit enable you to dial in your ideal tone. An effects loop, an auxiliary input, a headphone output, an extension speaker output, and an XLR direct output for connecting to a P.A. or recorder complete the package
