I had to go for other as I feel that the best bass OD I've ever used is a Roger Mayer Voodoobass. I've never ever heard a pedal that emulates natural tube overdrive so good. Turn the tone and gain up for some true bass fuzz! No other overdrive i've used keeps the low end as tight as this pedal. Probably my favourite pedal on my board. It's true bypass too.
