I have noticed when I strum the G and B strings together, open, it produces a weird reverb sound, even with all the extras turned off. It happens on every amp simulation, but is especially apparent on the overdriven ones. (Select a red amp) It's a warbly reverb that just makes playing sound unnatural when you're hitting both those strings.
Is this happening for anyone else? It's all I hear now when I'm playing through my ST. :(
