I just want to know the best way to add distortion to my bass amp sound. I have tried the built in distortion on my Ampeg BA210 and also tried various pedals but my tone seems to lose low end when I engage any distortion to it. I know there is a way to keep my low end just as it is and just add some distortion to it. So that the clean tone remains the same through it all and all that happens is distortion is added to the sound. Who knows how to do this?
