if you can play bass on a fender frontman 15g
you're going rape that little 8" speaker putting bass frequencies through it.
i think it'll be okay if you don't turn it up, cuz someone used my 15watt to play his bass once and it's perfectly fine
dont DO IT unless u wanna ruin it...u can do the viseversa tho
Yeah it'll work. But it won't be great sounding or healthy for your amp if you turn the volume up to much.
It'll most likely break it - which would be either a good or bad thing, depending on your point of view.
