Ryan Hewitt is well known for his work with such artists as The Red Hot Chili Peppers, Flogging Molly, Johnny Cash and The Avett Brothers.
He recently installed Moog's new 500 series module, The Ladder into his recording rig and had some great things to say about it.
Its a really powerful tone shaping tool. While I thought I would be using it like one would use a filter in a modular synth, I found more varied positions for it to play as an EQ and subharmonic helper. It's great for helping anemic drums explode, creating dub bass sounds and modern guitar textures. Pretty awesome and a great companion to my old Moog 3 band Parametric EQ!
