right into the amp - no humbucker guitars. Now the noise is pretty quiet - when i had one chanel set very clean - it didn't seem to do it on that channel.
we're talking about a faint noise... but it is just weird that it goes from dead quiet when my guitar is on "1" , to a slight noise when it is on "0".
I think it is probably the kind of thing I can ignore but I also wonder if some fuse or connection or cap or resistor is bad in there?
EDIT 12/15 - when I played it today, it didn't do this at all. mystery gremlin but amp seems fine (except for the rattling tube it came with)
