its funny that you ask this, because i just got out an old issue of GuitarPlayer magazine that has a review of the Johnson J station. It is a similar effect to the POD line6. these effects simulate different amplifiers and allow you to add effects like chorus, flange, reverb, and delay. You should know that the line6 is a proffessional quality effect (bands use them on recordings and live shows) and by this review i read, the j-station sounds comparable. I've heard nothing but good things about these the line6 and the j-station. people have told me that you can get ANY sound with them. you should look up their websites and compare prices.
