Am looking at one of these heads, never played one. Wondering how it compres to the RG100ES? Have only been able to listen to one on youtube, and you know how that can be. Anybody here have one and what are your thougts about it, pros and cons, so to speak. Thanks,Brad

Hey guys, this will be my first post. Have the XP version of the RG100ES and everything works fine with the head until you switch on the sustain/boost switch. The volume will begin loud and after awhile it will become much quieter and then get louder again, if you push or tap on the switch while it's quiet it will get louder.Has anyone ever run into a problem like this with this type head? Thanks for any help in advance!! Brad
