I recently tried out a Q-Tron + pedal and although I know it isn't designed to be a bass pedal I still liked the sounds I could get out of it and the fact that I didn't lose any low end. I would like to know if there are maybe some bass friendly alternatives?

You'd be surprised at how many guitar pedals work for bass aswel, multi effect processers for guitar rarely work for bass, there all for a very strict frequency, but singular pedals work well with bass sometimes, fuzz factory for example does well with bass :P Long as you dont oscilate for ages otherwise youll be picking bass amp peices out of the next street :P

Some OD pedals work for bass, thats about all i know
