So I'm looking for a pedal that'll give me a growl similar to Frodus's bassist on their album "And We Washed Our Weapons In The Sea", especially from the tracks "The Red Bull of Juarez" and "Year of the Hex". I would also like said pedal (if possible) to be able to just add a bit of an edge to the sound similar to Thrice's "Hoods On Peregrin" I've been looking at EHX's Big Muff Pi as well as EBS's ValveDrive. Any other suggestions? Anything with soundclips would be awesome. Thanks in advance guys.
