Matt got all the mods done to make his phaser and fuzz bass friendly. Both pedals were initially built for use with guitar and I picked them up to check them out. After some conversations with him he went to work and found mods to his original design that work a lot better for bass. He posted some youtube clips. fuzz phaser I'm having him do the mods to my pedals next week and when I get them back I will try to find the time to make some clips.
