Very small and light with superb sound amplification, 100% reliable after two years of use (about 300 gigs), can drive two cabinets via the two Speakon-style speaker outputs and patch into sound systems via the "Send" of the effects loop.

Other than hi-and lo inputs and dual voltage capability, its only "feature" is an effects loop, the "Send" of which I use occasionally to patch into a PA system. It produces an utterly clean, transparent sound, runs absolutely quietly and has ample power for my acoustic upright bass, driving my 8 ohm cabinet with 125w. The SL is a reliable, professional grade unit that delivers the goods.
