NAMM 2025: Pantera bassist Rex Brown has joined forces with Morley on a new signature wah pedal based on his long-serving Pro Series II unit, ‘Old Blue’.

Brown has been using Morley pedals since the 1970s, but reportedly picked up Old Blue at some point in the 1990s. Since then it’s found use on Pantera records, including The Great Southern Trendkill and Reinventing the Steel and has been a pretty constant feature on his live ’board, to boot.
