I ain't giving any pickguard a 5 star review. It does appear innocuous though. Easy to remove with care hopefully. I'll know in a few years. In general the 420 I bought has had a constant buzz on d string when I finger pick. Found on close inspection the wrap on that string, where it rests on the bridge is separated and broke down to the core wire. Using a pick it's kinda not there. Gonna play strings out@2 weeks. What gauge do you set up with? Should I keep this humidified if left out? One last thing this is a fantastic thing in a studio. It's stellar on a porch and rings thru the cacophony of sounds throw around. Thanks a heap
