i was given a gnx 4 full of mud from a flood that i took apart, jet sprayed, put in a bathtub with a paint brush to clean, dried in the sun & it was amazing for 3 months than nothing, kaput... not even a second "bath & shower" worked so i snagged a gnx 3 for $70... it has a defect that when you step on a pedal it takes a second or two to switch which makes it useless for onstage but mine gets a lot of studio use... i do all of the editing with a laptop...
