A POD is probably not your best bet. I would suggest a good overdrive pedal. The Boss Blues Driver is incredible (don't let the name fool you, it has an awesome overdrive). Also, look into getting a compressor, the MXR DynaComp is pretty cool. And maybe a chorus pedal and a delay pedal. That is pretty much all you would need for what you play. I hope this helps some. Good Luck.
