I like to practice at home with my electric guitar, but I have to keep the volume low, so I usually use headphones connected to my P.O.D. 2.0 guitar direct box. But sometimes I'd prefer to use speakers (at a volume comparable to an accoustic guitar).
As this is just a hobby, I don't want to invest a lot of money, so I've tried to simply connect the POD (headphone out) to the 2.1 active speaker system I usually use for watching TV. However, to my surprise, this gives me a lot of ringing/rattling/clanking - although I can turn the speakers up to a much higher volume when watching TV without these problems (I also simply connect the speakers to the headphone out there). So I tried reducing the bass and volume a lot, until the problems go away, but then the sound is really bad. It doesn't have anything in common with the sound I get from the headphones.
I always thought, that it should be possible to connect a Hifi system to a POD - but I must be doing something wrong?
