I just recently purchased a new bass with very high output. It's about 20dB higher on average than a bass with vintage jazz pickups. That amount of gain is causing issues with some of my pedals. So I am looking for a medium/high gain distortion pedal that will work with this bass without having to decrease gain from the bass radically. I probably need a pedal with high headroom for better dynamic response, possibly running at 18v. I also would like it to have decent eq options. I prefer a rat-type sound but am open to other ideas.
