I currently have the Broughton Audio JoshWah which has a good amount of gain in its own right that you can dial in to throw some dirt on the envelope filter & I also have a Smallsound/Bigsound Team Awesome! Fuzz Machine which has MASSIVE output... so much so that it drowns out my other pedals. I've tried it before & after the JoshWah in my signal chain. If it's before the Joshwah I can't get the filter effect but if it's after I can tease it out a little by using the blend knob on the TA!FM but I feel like the fuzz is too powerful to use in combination with my other pedals which has me looking for other fuzz options sooo I'm curious... what combinations of filter & fuzz do y'all use???
