Tortuga Effects Basswolf When Matt Johnson originally designed the Werewolf™ the plan was to create the most versatile overdrive and distortion for guitar all in one box. What he didn’t plan on was that it would also sound amazing on bass. Over the years he found that he sold just as many Werewolf™ pedals to bass players as he did guitar players. Although all of those bass players love their Werewolf™, it got him thinking that he should take some time to tweak the circuit specifically for bass frequencies. What he came up with was the Basswolf™ - a Werewolf™ that not only shines on bass but also really kills it on drop tuned guitar.
