Solid bass performance The RB1 is a super compact bass combo housing a custom designed 8" driver but don't let that fool you – it delivers a punchy 15 watts RMS of solid bass tone. The preamp features a powerful three band EQ, an on-board compressor and an internal limiter along with a mini jack headphone socket and mini input jack allowing connection of a media player to jam along with your favourite tracks. The RB1 features a dual-position cabinet design so can be used as a conventional stage combo or in ‘kickback’ position as a monitor.
