it comes with the M1 which has 3 LED lights. One for power, one for clipping, and one for protection. No bass knob but this is easily solved with an inline RCA style knob or in the way I went was with an EQ. I was exactly in your shoes about the bass knob but this issue is easily solved. In my case I went with an EQ so this way I could have more tuning ability. One seller currently has the smart 5’s for $458!
