I just got a Boss Bass Overdrive and love it. Others may not agree but it was $50 and solid as a rock. As little or as much dirt as you want. 2 band eq and blend knob.
Nothing wrong with that pedal at all. It was my first effect purchase 14 years ago. Served me well for many years. There are definitely a LOT of haters here when it comes to that pedal. I think the name is what throws people off. It should really be called a bass distortion, not bass overdrive.
