Over the years, Nashville session ace Brent Mason has gone through countless combinations of pedals. Currently, he’s using a simpler system mounted to a large Trailer Trash pedalboard. The signal chain starts with a Dunlop MC404 CAE wah going into an Ernie Ball 6166 volume pedal. Next is a Wampler Ego Compressor, a Boss GE-7 Equalizer customized by Analog Man, a Visual Sound V2 Truetone Clean Boost, an Xotic Effects RC Booster, an Xotic Effects BB Preamp, and a Creation Audio Labs MK 4.23 Clean Boost. For dirt, there’s a Way Huge Red Llama Overdrive followed by Mason’s signature Wampler Hot Wired V2 Overdrive. All of Mason’s clean-boost and dirt pedals are accessed via a no-name loop switcher that Mason bought “from a dude on eBay.” A separate loop switcher controls Mason’s trippier effects—specifically, an Electro-Harmonix Stereo Memory Man and a Pigtronix Tremvelope. Next in line are Wampler Faux Tape Echo and Faux Spring Reverb stompboxes, and the final effect is an old, tried-and-true Line 6 MM4 Modulation Modeler. Mason uses a Boss TU-2 tuner and powers the whole shebang with several Voodoo Lab Pedal Power 2 units.
